Not printing true black

Post by xtremegraphicstint » Mon Apr 16, 2018 10:09 pm

I'm using CorelDraw 12 with CYMK pallet. I export the file as an EPS to versaworks on my roland soljet pro III xc540. I'm making a basic sign with a colored background but with black boxes around the text and black text. There seems to be almost like an outline of white around the black text/boxes meeting other colors.

Ive looked into color management to select preserve black option but the screen shot below is completely different than what I've found online.

Publish to PDF with X1a as your preset.

Set Sign & Display as your Color Management setting in VersaWorks.

today here in michigan it was quite a bit warmer than what it was when i printed the 2nd time with it turning out perfect with the heat settings higher. with the same heat settings today it resulted what is above. so i adjusted the heat settings lower than what they were the 2nd time and now the print is turning out perfect. so does it make sense to say the heat settings have to be lower during warmer months even though the media/printer is in a controlled/heated environment?

Sign & Display preserves pure colors instead of simulating offset print.

What are your heater settings? The best combination is 95 degrees F for PRINT heater and 104 degrees F for dryer. You shouldn't need to change anything unless it's really cold or really hot in the printing room.

The fuzzy edges you're getting are from head carriage optical registration system called the encoder. It's an optical sensor reading the thin lines printed on a transparent film mounted on top of the carriage rail inside the printer. The lines are really thin, 180 lines per inch so the film has to be clean and free of dust/hair and hopefully scratches. A service tech usually checks and cleans it when servicing the printer. If the encoder strip and sensor are both okay then it's probably a drive belt or a scan motor issue.
