A Digital Printing Network
Just wanted you guys to look over the picture below and let me know if you have any idea as to what causes the "splatter" when I print pure black (left alphabet, first image). We have had this problem for quite some time and we just work around it by printing a muted black (right side, first image). As you'll notice the splatter follows the print head from right-to-left and back during the printing process. Like I said before this has been going on for a while so the machine has been cleaned many times both internally and manually. When I asked Imprintables Warehouse about it in the beginning the only answer they had was static electricity. I have tried the machine in different rooms, under different conditions (humidity, temp., etc.) and nothing really changes. Sometimes it looks worse than others but it has never fully stopped. The test print is pretty clean but if you all would like to see one let me know and I'll run one when I get a chance. Finally, this happens across all media types (quick print, oracal, durasol, paper, banners) and profiles (some are worse than others). Thanks in advance for your help.

If Imprintables is saying it is static give this a try. Use a dryer sheet to wipe down the rollers and the unheated potion of the printer the media lays on when printing. If it is static this should remove it and give a good print.
On another note I've seen similar issues with a dirty encoder.
Irving, sorry for hijacking this thread...but you mentioned using prepress for raster and max impact for vector. I never knew or heard about this, and 95% of my work is all vector. I've noticed colors are grainy (like solid brown or orange) and yet some of my files with photoshop images print out brilliant pure colors. Is this the missing link to getting crisp images?
Roland held an excellent webinar on color management. They did a great job at explaining the Max Impact, Sign & Display, and other settings as well as the difference between perceptual and colorimetric. They explained how the printer was reading the information and translating it into CMYK and how that was affecting your color gamut.
I would highly recommend contacting Roland to see if you can get access to any of their materials on the subject, because it was a really interesting and useful webinar.
There was a link I recently got to access the webinar achives, I'll see if I can dig it up
I attended that Webinar you're talking about, CB
It was interesting
