We've been having problems with many PDFs not printing the correct color on our Lanier 2138.

What is happening is that colors look fine in InDesign and Acrobat on screen (we used Adobe Gamma to adjust monitors), but printed they are, like, super-saturated, way more powerful than they are supposed to be. This problem is completely alleviated by using "print as image" but sometimes the output is truncated (at 1200dpi), and using this option seems to defeat the purpose of having a Postscript printer-no?

We have tried printing to other printers (HP Designjet) and the colors are spot-on so I have a feeling it is possibly something in the Lanier PS RIP--let's say it's not the best (and my boss wouldn't splash out on the Fiery version of the printer). Anyone have any ideas?


...As a little background, most of our files blend complex vector graphics from AutoCAD (placed in ACAD as RGB/Grayscale PDFs), RGB images and text/graphics in InDesign. We also make considerable use of transparency and color blending in InDesign.

All of our PDF files are created via InDesign 2.X either through "Export" or print to Distiller (we have the version that comes with Acrobat Standard 6.0). All our source images, ID colors, transparency blend space, and output are RGB, we've been quite careful to do that having read a lot of these forums. We even use RBG black for text. We tend to avoid Color management profiles as we're not really smart enough/don't really have enough time to experiment; and in my experience they ususally mess everything up if used wrong.

Possibly unlike many PlanetPDF members our output is entirely composite and we are not concerned with press or prepress.
