Adrian Monk

Adrian Monk, Software Developer at Global Graphics Software

Meet Adrian, software developer at Global Graphics Software:

What is your background?

My career in software and computing started when my brother first bought me a computer to help with my homework. Since then, everything I’ve done has been geared towards helping me achieve my dream of writing software and working in a technical environment.

I have a BSc in computer science and over nine years of experience developing software in the engineering sector.


What were you doing before Global Graphics Software?

Before I started at Global Graphics, most of my working life was spent at a software company in Cambridge called AVEVA in their platform group, working on the fundamental frameworks that underpinned all of their products.


What’s the best thing about working at Global Graphics Software?

There are many great things about working at Global Graphics I’m not sure where to start, but to list just a few:

  • People – The people I work with on a day to day basis are all incredibly talented with a wide range of experiences. The company is small enough that we really do foster a family feel to the environment.
  • Interesting problems – We are on the bleeding edge of printing technology, trying to solve problems that can improve the output of our customers’ hardware by using software and science.
  • Environment – We have a modern, open plan office that really encourages collaboration. We get a great selection during our free breakfast and hot/cold drinks when we want them.
  • Freedom and trust – It’s clear that Global Graphics wants to empower its developers. We have say over all aspects of our work, from the technologies that we use to the processes we follow.

What has been your career path since joining Global Graphics Software?

Since I joined the team in March 2018, I have been the hands-on team lead and Scrum Master for the ScreenPro™ team. I am responsible for facilitating the Agile processes we follow and I work closely with stakeholders to ensure that the team always has what it needs to develop a great product. I even still write code, albeit less than I used to.

What is the environment like?

The environment is open, inviting, friendly and full of talented people. Global Graphics offers flexible working and work from home opportunities. We have a fully stocked kitchen and a full-size table tennis table.


What is the most exciting thing about your work?

We are solving big issues for our customers, improving the quality of their output to the point where we can physically see the difference.


What projects have you been involved with?

Since joining the team we have released several updates to the ScreenPro application and now we are looking at future projects, such as how we develop the PrintFlat™ technology.


Have you taken part in any of the social events?

I have been a member of The Shed project since its creation this year. This is a fantastic opportunity for staff to play around with technologies that we don’t normally use in our day-to-day roles. My project, for example, is an automated plant management system which uses a Raspberry Pi and various sensors to manage tasks like watering.


Have you taken advantage of any of the company benefits?

Since I’ve only been here a short time, the main benefit I’ve taken advantage of is the company’s Perkbox membership, which offers discounts on lots of things including cinema tickets which is extremely handy!


What keeps you here?

There are a number of things that keep me here, but mainly it’s the continuous flow of interesting problems to solve and the great team atmosphere we have built.

Ben Gilbert

Ben Gilbert, Principal Software Engineer

We chatted to Ben Gilbert, principal engineer, about his work at Global Graphics Software:

How did you come to work at Global Graphics Software?

I joined Global Graphics Software following a 10-year career in the Royal Air Force. I had always been interested in computers and programming so I decided to make this my career upon leaving the service.

What has been your career path since joining Global Graphics Software?

I joined as a technical support engineer, providing first line support to our gDoc Application Platform (GAP) SDK customers. I also started developing sample code and automated test harnesses for the GAP team to use.

I then moved into a software development engineer in test role, where I became responsible for all test automation within the applications team across all products.

I became a full-time software developer on the applications team and worked on our GAP SDK as well as a short time working on our gDoc Core (now Mako) SDK.

I then moved to the Technical Services team, as a senior software engineer, where I was involved in many customer-driven projects – working directly with our customers’ engineering teams.

My current role as a principal engineer is to architect solutions for our customers and be responsible for design, implementation and delivery against tight deadlines.

Most recently, I have been working on our ScreenPro™ Direct solution. This began as a single customer project, with the goal of driving print data to hardware in real-time. It has now matured into a product being used by multiple customers.

How long have you worked here?

Five years.

What is the environment like?

Relaxed and informal. We are trusted to perform our work to the best of our ability, so there is little micro-management.

What is the most exciting thing about your work?

Helping our customers solve real-world problems and helping them ship their products faster. It’s a good feeling knowing that our customers are running code from Global Graphics Software, that is allowing them to achieve their vision and business goals.

What keeps you here?

The people I work with day to day, plus the freedom to make decisions (and learn from mistakes). Career progression is very good. If you make it known where you want to go, Global Graphics Software will try it’s best to get you there.

Matt Gosnell

Matt Gosnell, IT Director at Global Graphics Software

Here, Matt Gosnell, IT Director, tells us about life at Global Graphics Software:

What is your background?

I started my career in IT because my mother said I needed to get a job! I studied photographic and digital media at Anglia Ruskin University but had always had an interest in computers. As a child, my best friend’s dad was a computer engineer and playing games in the early 90’s was my childhood. By my late teens, I was building my own computers and was more interested in gaming and the digital side of my degree than being in the darkroom.

My first job in IT was at Bassingbourn Village College – I was the onsite technician who helped diagnose a variety of IT problems. It was a great start and I learnt a lot ‘on the job’. After a couple of years I moved on to an IT support company, where I would visit all kinds of companies for onsite assistance. Every day brought a new problem to solve. It was hard work but again I learnt a lot. In 2009 the excitement of a new environment each day wore off and I decided to make a jump to an internal IT department where I could make a difference long term, that’s when I joined Global Graphics Software.

What’s been your career path since joining Global Graphics Software?

I started working at a junior level in a team of four. After two years, I was promoted to manage the team. We were a much bigger company then and it was back in an era where you had to go to IT to get stuff done – it was a very busy department. I’ve since grown with the company, taking on more responsibility over the years and have been IT director for almost three years now.

Today, the company is very different; instead of having a single company to look after we also have our sister companies – so it’s a challenging environment. My goal is to try and achieve more consistency in IT among all the businesses.

What’s the best thing about working at Global Graphics Software?

For me the best thing about working here is that I’ve been given the opportunity to grow. I’ve always worked hard and strived to better myself and Global Graphics has encouraged me to do that. I’ve been on a fair few IT training courses over the years. Nowadays I try to go on a course once a year to keep my skills sharp.

What is the environment like?

It’s very friendly and has a flat management structure, i.e. we all sit amongst each other, whether management or not.

What is the most exciting thing about your work?

For me the most exciting thing is being at the forefront of IT technology. I have to keep abreast of technological change and how this can benefit the businesses that I represent.

Are there any big projects you’ve been involved with?

I’ve been involved in many big projects mainly because IT tends to be at the heart of the business. For example, we’ve moved offices, both in the UK and abroad, developed cloud and disaster recovery solutions, as well as integrated purchased business into the Global Graphics Group.

Do you take part in any social activities?

I’ve been part of the Global Graphics cycling group. We did quite a few London to Cambridge cycle rides. I also enjoy taking part in The Shed, a creative environment where we are free to work on projects to learn new skills. I am an active lead in my own project and am currently building a temperature-controlled fan array using an Ardunio Uno. As a result I’m learning all about electronics!

What keeps you here?

My job has changed so much over the last ten years and this has meant I’ve never had time to get bored. I’ve been given more responsibility and the opportunity to progress, and of course IT has changed so much, it has kept me on my toes. I’m given plenty of support, but I’m also trusted to make decisions on my own.

I have the freedom to develop as I’ve still got a lot to learn about directing a business in its goals. As the company grows my role grows – I have more to manage. My aim is to continue to grow. I’m in control of where we’re going and that’s a positive for me.

Questions from the Inkjet Conference, Düsseldorf

The Inkjet Conference Düsseldorf has been and gone for another year and we’re already looking ahead to the 2019 events that will be organised by ESMA.

This year delegates in the audience were able to submit questions via an app for the first time. I’m grateful to the IJC for sending me the questions that we either didn’t have time to cover after my presentation, or that occurred subsequently. So here they are with my responses:

Is it possible to increase the paper diversity with software by e.g.  eliminating paper related mottling?

Yes, we have yet to come across a media/ink combination ScreenPro™ will not work well with. The major artefact we correct for is mottle. This may mean you can print satisfactory results with ScreenPro on papers where the mottle was unacceptable previously, so increasing the diversity of papers that can be used.

It sounds like ScreenPro is very good at tuning a single machine. How do you also then match that output quality among several machines?

There are two technologies in ScreenPro, the screening core itself with the Advanced Inkjet Screens (AIS), and PrintFlat™ to correct for cross web banding. ScreenPro generally improves print quality and Mirror and Pearl screens (AIS) work in the majority of screening situations. PrintFlat, however, needs to be tuned to every press and if the press changes significantly over time, if a head is changed for example, it will have to be recalibrated. This calibration actually makes subsequent ink linearization and colour profiling more consistent between machines as you have removed the cross-web density fluctuations (which are machine specific) from the test charts used to generate these profiles.

“We haven’t found ink or substrate that we couldn’t print with.” Does this include functional materials, such as metals, wood, rubber? or is it limited to cmyk-like processes?

No – with ScreenPro we have only worked with CMYK-like process colours, i.e. print that is designed to be viewed with colour matching etc. ScreenPro is designed to improve image quality and appearance. I see no reason why ScreenPro would not work with functional materials but I would like to understand what problems it is trying to solve.

What is the main innovation of the screening software in terms of how it works as opposed to what it can do?

“How it works” encompasses placing the drops differently on the substrate in order to work around common inkjet artefacts. The innovation is therefore in the algorithms used to generate the screens.

Advanced Inkjet Screens are standard in the ScreenPro screening engine

 

Simple VDP support

VDP is a topic that has the potential to get people very excited. We are no exception. For instance we were delighted when Mark Andy told us that our technology reduces process and RIP times on the Digital Series HD by 50% even with full color, every-page-different.

Confident of the benefits print shops would experience if they could take on higher premium personalised jobs, we made sure from the early days, that our technology would be a) able to handle variable data in “regular” flavour PDFs by intelligent rendering b) be PDF/VT compliant (since IPEX 2010) and capable of high-speeds without sacrificing quality. And now there’s a new development that we’ve introduced this year with the launch of Version 12 of the Harlequin Host Renderer in April 2018.

What about when your VDP workflow doesn’t really benefit from PDF/VT but needs a lighter weight solution for adding text, graphics and barcodes?
Harlequin Host Renderer 12 now supports Dynamic Overlays for these use cases. Some applications such as packaging, labels and industrial print, require a simple form of VDP support. This might be where a single background page is combined with overlay graphics that are selected on the basis of a data file supplied in a format like CSV. Serial and batch codes can be added using dynamic counters without writing values to a CSV first. Support has been added to apply overlays on top of a single page PDF file to add simple serial numbers on labels or QR codes for personalized URLs, postal barcodes and addresses on envelopes.

Secure tickets

This secure ticket is generated with in-RIP bar-code support where data is read dynamically from a CSV file.

The example shows:

  •  A complex guilloche pattern in the background
  • Two lines of micro text identifying the recipient by name
  • A QR Code encoding a personalized URL (PURL)
  • The Global Graphics ‘g’ is painted in the centre of the QR Code
  • A six-character code in which each character is drawn with one of six different colours

Folding cartons

The background for this image comprises three folding cartons using nested imposition.

The overlay includes:

  • The first name of the recipient in large white text with a silver border
  • The full name of the recipient together with their city and state
  • A line of microtext showing their full name repeated to fill the space available
  • A QR Code recording a personalized URL (PURL), with a Global Graphics logo placed over the centre of it
  • The flag for the state of the recipient

 

 

 

 

 

 

Lesley Whitfield

Lesley Whitfield, software developer at Global Graphics Software

We chatted to Lesley Whitfield, software developer in our Wilmslow office, about her work at Global Graphics Software:

What is your background?

I was always interested in maths and science then discovered engineering at university, eventually ending up with an Open University degree in maths and electronics.

How did you come to work at Global Graphics Software?

I was looking for a new challenge after working on a smaller product.  Although I was also offered the opportunity at the time to be a bigger fish in a smaller pond, I chose the more technically interesting job at Global Graphics Software.

What were you doing before?

A whole range of jobs from stress analysis in the aerospace sector, instrument safety, embedded software for smart meters, to software for direct mail.  Before joining Global Graphics Software 18 years ago I tended to move on to something new every couple of years.

What’s the best thing about working at Global Graphics Software?

Working in a highly motivated and skilled team that is serious about doing the best possible job.

What has been your career path since joining Global Graphics Software?

I joined as a software developer helping out with our color management technology including some of the more mathematical aspects. Later I wrote the color interpretation code for XPS (one of the Page Description Languages we support), then was lucky enough to join the PCL team from the start. This allowed me to play a significant part in interpreting the specification and designing the way the PDL code interacts with our underlying core technology, which in turn was very useful when I was part of the team trying to speed it up. I have swapped back and forth between a couple of teams, tending to specialize in one or two main areas but helping out where required including, unusually, a stint as developer in support. The last six months I have been excited to work on our Harlequin VariData solution where it is possible to make a very big difference to performance and hence the customer experience.

What is the environment like? 

Hardworking, friendly and helpful. Ideas are discussed on their merits so everyone has a chance to contribute. Developers have a good relationship with QA who take an active part in our scrums, and also with support. Working hours are fairly flexible and evenings and weekends are respected. The office can be a little quiet sometimes, but everyone is willing to discuss technical issues and most people are up for a chat in the kitchen. We are small enough to get to know people across the company. There are various social events throughout the year.

What is the most exciting thing about your work?

Probably knowing that the software I’m writing today will soon be allowing huge presses all over the world to operate accurately and at high speed.

What projects have you been involved with?

The most exciting project I was involved with was when we had six months to make our embedded RIP go three times faster across a wide range of jobs.  This was incredibly challenging but as a team we were determined to do it, and thanks to our ingenuity and diverse skill set we succeeded!

Have you taken advantage of any of the company benefits?

Yes, I am a keen sailor and volunteer as sea staff with Ocean Youth Trust Scotland. I normally do at least a week each year and put my paid charity day towards that (http://oytscotland.org.uk/).

In addition, I always take up the opportunity of a week’s unpaid leave in addition to my paid holiday.

Global Graphics Software has also supported me over the years in achieving my personal goals. I have been studying Japanese as a hobby with Manchester University since 2015, and last year I was able to spend two months working in our Tokyo office which greatly benefited my Japanese. I just got my final exam results and am very pleased to say I passed!

What keeps you here?

Working here gives me an opportunity to work on the type of problems that I enjoy solving, with friendly colleagues who are highly motivated to do a great job. I feel my work is appreciated and relied on. Recently Global Graphics Software has been getting into a variety of new areas such as multi-level screening and inkjet technologies, and that can only mean more opportunities in the future.

ScreenPro™ makes a real impact on those hard-to-solve killer jobs

By Tom Mooney, product manager for Global Graphics Software

I’ve just returned from a road trip in the US to inkjet press manufacturers who are all interested in using ScreenPro.

The meetings have gone in a very similar manner with the opening line: “We have a print shop that wants to print this job, but take a look at this area.” They point to an area of the image, usually in the shadows, and it is either a muddy brown mess or crusty and flaky, the typical ‘orange peel’ effect. We all agree the print is unacceptable and cannot be sold, so we discuss what can be done.

Firstly, we look at the ink limitation, but this kills the color saturation in the rest of the print. We look at color management and under color removal, but this only moves the problem to a different area on the image.

Then we see what ScreenPro can do.

We try our Advanced Inkjet Screens™ and use Pearl screen on the muddy mess and Mirror on the orange peel. This does the trick and makes the prints acceptable, so the print shop can sell that print job.

As long as this quality threshold is met the customer is happy. This quality is achieved by a combination of hardware, media and ink and software. Color management is only part of the story with the software – ScreenPro makes a real impact on those hard-to-solve killer jobs.

ScreenPro’s Advanced Inkjet Screens solve two common problems: Mirror avoids orange peel mottle on non-absorbent, poorly wettable substrates and Pearl counteracts streaking on reasonably absorbent and/or wettable substrates
