Release Notes

4 Release Notes for Epson Variable Size Droplet Printers

4.1 HEDS1 and HEDS2 screening

Unlike the standard Epson plugin, the ProofReady plugin for Epson VSD

printers does not perform EDS screening. You must install the new Harlequin

1-bit Error Diffusion Screening (HEDS1) and Harlequin 2-bit Error Diffusion

Screening (HEDS2) plugins to use in-RIP EDS screening. The in-RIP EDS

screening plugins require version 5.5r1c or later of the Harlequin RIP.

Note that the HEDS2 plugin must be installed and enabled when sending

output to some device types, such as those for the Epson Stylus Pro

4000/7600/9600/10600. Otherwise, the RIP may unexpectedly quit or freeze.

For this reason, we have supplied an installer for all supported platforms, that

can be used to install the Epson VSD plugin, as well as the HEDS1 and HEDS2

plugins. You should use a password file to enable the ProofReady and screen-

ing plugins before starting the RIP. You can request a password file from GGS.

Please refer to the User Manual for full details on how to install and enable the

plugins. Section 5 on page 7 describes the supplied documentation.

4.2 Limited color gamut of Archival inks

When proofing on certain media using the Epson Archival

™

inks available

with the Epson Stylus Pro 5500, 10000, and 10600 we have found that the color

gamut of some types of commercial printing on high grade paper stock is not

covered. Additional testing may be required based on your particular

requirements.

4.3 Increased memory requirements

The amount of data that needs to be sent to the Epson VSD printers is signifi-

cantly larger than for standard Epson printers, because of the use of 2-bit

screening and other factors. For example, the Epson Stylus Pro 10000 has 180

nozzles, as opposed to 96 nozzles, and the Epson Stylus Pro 7600/9600 print

using seven inks (CMYKcmk). As a result, additional memory may need to be

allocated to the RIP. The main manual provides some suggested memory set-

tings that you may want to try initially.
