Printing pixels and weird colours

kristof1995 · ‎03-15-2021

Hello there. I have a question as I am at a loss at this point where to search for the issue anymore.

I am trying to Plot a A0 with 2 Large pictures but im getting always huge chunks of pixelated areas and a weird colour in those areas as well. I tried to upscale the DPI to 600, I changed all Ink patrons already, tried to print it as a smaller sample and it didnt have any issues.

Im printing out of a PDF

In the showcase the picture looks normal the issue happens only when its plotting it.

Edit: The rest of the printed picture looks normal and sharp just a few areas have that issue especially when its about the colour Brown

What drivers are you using and have you tried a different PDF program to print from?

I tried 3 Different PDF Programs already and none helped.

Not sure if these are the drivers but:

Drivername: printqueue.inf

and the above mentioned driver name is installed in PS3 and HPGL2

I found the issue. While printing I needed to set the Bit map to 16 bits to have shadows better printed out.
