Farewell “Harlequin Host Renderer”, hello “Harlequin Core”

We’ve now been shipping the Harlequin Host Renderer™ (HHR) to OEMs and partners for over a decade, driving digital printers and presses. Back then Harlequin was our only substantial software component for use in digital front ends (DFEs), and we just came up with a name that seemed to describe what it did.

Since then our technology set includes a component that can be used upstream of the RIP, for creating, modifying, analyzing, visualizing, etc page description languages like PDF: that’s Mako™. And we’ve also added a high-performance halftone screening engine: ScreenPro™.

We’ve positioned these components as a “Core” range and their names reflect this: “Mako Core” and “ScreenPro Core”. We also added higher level components in our Direct™ range, for printer OEMs who don’t want to dig into the complexities of system engineering, or who want to get to market faster.

Harlequin is already part of Harlequin Direct™, and we’re now amending the name of the SDK to bring it into line with our other “Core” component technologies. The diagram below shows how those various offerings fit together for a wide range of digital printer and press vendors (please click on it for a better view).

So, farewell “Harlequin Host Renderer”, hello “Harlequin Core”.

Ditch the disk: a new generation of RIPs to drive your digital press

Vast amounts of data can slow down your digital press resulting in wasted product or delayed delivery times.
Vast amounts of data can slow down your digital press resulting in wasted product or delayed delivery times.

In this post, Global Graphics Software’s product manager for Mako, David Stevenson, explores the challenge of printing large amounts of raster data and the options available to ensure that data doesn’t slow down your digital press:

The print market is increasingly moving to digital: digital printing offers many advantages over conventional printing, the most valuable of these is mass-produced, personalized output making every copy of the print different. At the same time  digital presses are getting faster, wider, and printing at higher resolutions with extended gamut color becoming common place.

To drive the new class of digital presses, you need vast amounts of raster data every second. Traditional print software designed for non-digital workflows attempts to handle this vast amount of data by RIPping ahead, storing rasters to physical disks. However, the rate at which data is needed for the digital press causes disk-based workflows to rapidly hit the data rate boundary. This is the point where even state-of-the-art storage devices are simply too small and slow for the huge data rates required to keep the press running at full rated speed.

This is leading to a new generation of RIPs that ditch the disk and RIP print jobs on the fly directly to the press electronics. As well as driving much higher data rates, it also has the benefit of no wasted time RIPping ahead.

As you can imagine, RIPping directly to the press electronics presents some engineering challenges. For example, two print jobs may look identical before and after printing, but the way in which they have been made can cause them to RIP at very different rates. Additionally, your RIP of choice can have optimizations that make jobs constructed in certain ways to RIP faster or slower. This variability in print job and RIP time is a bit like playing a game of Russian roulette: if you lose the press will be starved of data causing wasted product or delivery delays.

With a RIP driving your press directly you need to have confidence that all jobs submitted can be printed at full speed. That means you need the performance of each print job and page to be predictable and you need to know what speed the press can be run at for a given combination of print Job, RIP and PC.

Knowing this, you may choose to slow down the press so that your RIP can keep up. Better still, keep the press running at full speed by streamlining the job with knowledge of optimizations that work well with your choice of RIP.

Or you could choose to return the print job to the generator with a report explaining what is causing it to run slowly. Armed with this information, the generator can rebuild the job, optimized for your chosen RIP.

Whatever you choose, you will need predictable print jobs to drive your press at the highest speed to maximize your digital press’s productivity.

If you want to know more about the kind of job objects and structure that can slow RIPs down, and the challenge of producing predictable jobs, download this guide: Full Speed Ahead – how to make variable data PDF files that won’t slow your digital press.

Connecting print to the Smart Factory

This week WhatTheyThink launched its 2021 Technology Outlook – a resource guide designed for you to quickly learn about new innovations from industry analysts and thought leaders. It includes five technology focus areas: digital printing, labels & packaging, software & workflow, wide format & signage and textiles & apparel, and finishing.

As part of the software & workflow technology focus, David Zwang of WhatTheyThink chatted to our VP of products and services, Eric Worrall, about digital front ends (DFEs), the elements that comprise a DFE, and the recent launch of Global Graphics’ SmartDFE™, a complete single-source software and electronics stack that does everything from job creation through to printhead electronics, and a vital component in the smart factory of the future. Smart factories are designed to autonomously run the entire production process and this will include the print subsystems.

Choosing the software to drive your digital inkjet press

When developing your first or next digital press, the software you use to drive it will be a key factor in its success, both for the data rates and output quality you can achieve. The time it takes to get your press to market based on the engineering effort involved to deliver and integrate that software is also a consideration.

A simple user interface to get  you started

The Press Operator Controller (POC) is an example front end or user interface available with Harlequin Direct™ , the software solution that drives printhead electronics at ultra-high data rates while retaining high output quality. The POC provides you with an initial working system, so you’re up and running without any significant in-house software development. We provide you with the source code so that you have the option to update and integrate it as part of your production system.

I have created a short video to show you its main functions:

PDF/VT – bringing all the advantages of PDF workflow to the world of variable data printing

Martin Bailey, CTO, Global Graphics Software

Standards for variable data printing (VDP) have come a long way since the first work by CGATS to develop a universal delivery format in the late 1990s. In 2010 the International Standards Organization published the PDF/VT standard, marking the first really effective specification for a reliable, vendor-neutral exchange of variable data jobs, both within and between companies.

A special type of the PDF file format, PDF/VT is specifically used for variable data and transactional printing in a variety of environments, from desktop printing to high volume digital production presses. Built on PDF/X, it therefore brings all the advantages of that standard in enforcing best practices for reproducible and predictable color and appearance to the variable data and transactional print worlds.

The industry is gradually realizing its value to improve quality, competitiveness and productivity, and I’ve been working with the PDF/VT Competence Center, especially with Christoph Oeters (Sofha), Paul Jones (Teclyn bv) and Tim Donahue (technical consultant) to produce a new set of Application Notes highlighting the benefits of using PDF/VT and the workflows that it enables.

The Application Notes explain how to make the highest quality and most efficient PDF/VT files to achieve the required visual appearance of a job, so if you develop software to read and write PDF/VT files, for example in composition tools, RIPs, digital front ends and imposition tools, or if you work on print workflow integration, you’ll find the notes really beneficial. They also show how document part metadata can be applied and leveraged for VDP specific production workflows.

Of course, there are wider benefits to using PDF/VT: The adoption of PDF/VT will allow the industry to finally move towards a reliable, vendor-neutral exchange of variable data jobs, simplifying the process of variable data printing significantly.

The application notes are free to download, pick up your copy here: http://www.pdfa.org/publication/pdfvt-application-notes/.

Let me know what you think of them – feedback is always welcome.
