Aloha from Maui :)

Our shop uses Versaworks 6.8 and prior to that 5.something with a Versacamm SP-540i. We've had problems with printing colors in the past, and while we've learned a lot in the past year? We have issues at times with getting colors quite right.

For instance, if we print shades of K at the higher densities there's a reddish tone to it. We had one large job that we really had to fight on this, and eventually gave up once we got to "close enough."

We printed some CMYK swatches with 100% of each, plus 80%, 70%, 60%, and 50% swatches. When we look at those swatches they all have at least two of the other colors in there.

Color Management is on Pre-Press General. We don't mess with those settings because we don't know what they do or how they work.

We have a color laser printer that has similar issues in that sometimes the profiles try to be a little too "smart," but there we can at least turn off color management.

For what’s it’s worth, we’ve only used RGB or PMS colors for the past decade+ when printing to the Versacamm and have had little or no issues.

I’ve  found the VW RIP does a fine job with converting the color palettes and helps eliminate the more restrictive color gamut inherent to a CYMK palette. In the rare case that we do use a CMYK user provided design........the colors are, almost always, theory, it’s almost like a double RIP conversion.

May as well start with a broader gamut before the conversion, in my mind.



We just started learning how to adjust PMS colors and are fairly happy with that process.

The main thing is sometimes we do need pure C, M, Y, or K. When this happens the color is "dirty" with other colors. If I need 100% yellow, I need 100% yellow, you know? If something is 80% K then I don't want the printed color to be a dark reddish gray.

Samuel, do you have the RGB default palette opened in Corel?

.......and have you tried printing 100% yellow from there?

Also you can (and probably should) print color palettes out on different media so you’ll always have a reference point to look at when you get those pesky color shifts.

Open Corel’s Macro Manager, select the palette you want to print in the drop down list of your opened palettes and voilé!

you’re in business!


Here’s another screenshot from an older version of Corel. Not sure how familiar you are with Corel......but just to make you crazy, different versions have slightly different road maps leading to the same end point. (sigh)

.........try again


We use Adobe Illustrator - I'll see if I can do that or approximate it.

We generally don't work in RBG because all of our machines have RIPs that work in CMYK, plus sometimes jobs have to be sent out to be done on press.

Our Versaworks is on a Windows computer, whereas all our production machines are Macs. Our shop does large format plus business printing, with our bigger customers having their own style guides we keep to. So we keep everything in Adobe for internal consistency/versatility, exporting to PDF, then importing those to the respective RIPs (Versaworks, iQueue, and Fiery).

Based on my experience, it /seems/ like Versaworks has something automatically doing a conversion even though one isn't needed. I've already tried eliminating our PDF export as a factor by creating a "No Color Conversion" profile. We recently ran into a similar issue for one print job on a our production laser printer and Fiery, so that was my first step here :)

Just adding 2 cents with the jist of the convo.

If you use CMYK expect dirty - If you print white on your non white printer it will try and make white with a mosaic of other colors. 

Use RGB, PMS, or Roland color palette. Search this site for many posts on it.

The Roland Ks will not mix the other colors.

Also on the quality tab, look for color management and go into the properties and select preserve primary colors - that will prevent the mixing of colors in your cartridges.

Ensure you keep current captops for that helps also.

Back to Lady Di.

I will try the "Preserve Primary Colors" tomorrow (almost the end of our day!). Hopefully that will be the fix.

Our white areas are actually fine! Oh, how I wish we had a printer that had additional channels! Santa skipped that part of my wish list last year ;)

Thank you. While I've been doing this for a while, I'm still quite new and literally don't know how to phrase searches on this. Hopefully I'll be able to catch up in that regard.

Great to read. Just remember in your white areas, leave that blank and the white will be the media. A small but important step.

We always use "paper" (ie, don't put anything there" for white. Our actual blank areas are fine :)

I know there ARE printers that can do print white (and metallics, and goodness knows what else - curry?), but sadly we don't have one of those super-cool printers :)

Tested: PRESERVE PRIMARY COLORS was the solution we were looking for.

I copied Pre-Press' settings and made a custom profile that was identical but had Preserve Primary Colors checked. We did a test print of our CMYK swatches (100, 80, 70, 60, 50%) and everything was clean. No mixing of colors.

I still have a lot more learning to go :)

By the way, what do you mean by "Ensure you keep current captops for that helps also."? Are you referring to the tops of the sponges where the heads rest/drain/clean when not in use?

Sometimes I speak NY - so ensure your captop is not more than a year old. Old captops put wear and tear on the head and allows ink to dry in the nozzles so you do not get full ink distribution.
