TOPIC: Printing Pixelation Issue

I have used Signlab for a long time now but cannot get good results from its inbuilt RIP.
So what I do is save the file to be printed as a level 3 EPS and export it to Wasatch our printing RIP and most of the time it behaves itself.
But when printing files such as large vehicle wraps with complex fades, shadows, effects and clips it makes an awful mess.
The file has pixelation in certain parts and in others it is perfect.
This is causing some serious issues and wastes some expensive print material.

When importing the EPS file back into Signlab you can clearly see the pixelated parts which have been recreated as raster and the vector image is now to the back.

Can someone please help?

Thanks

Hi Sean,
Can you send me the CDL file and the EPS created from it? Use WeTransfer or something similar if the files are large.
Send them to support "at"cadlink.co.uk

Hi Ray

Have you had any joy with the files I sent?
I have to get this printing tomorrow morning!!

Cheers
Sean

The fact that you get an image produced in the EPS file is because there is a transparency in the file, when the eps is produced the transparent object and any objects underneath it get flattened (rendered to an image) as they cannot be translated to vector objects, hence the bitmap and vector combination in the files.

If you go to Options > PostScript Setup > you can uncheck the option for “Intelligent Resolution reduction”, you then have 5 resolution options on the sliding scale that you can choose. I would suggest just switch off the resolution reduction and try that first, and then try adjusting the resolution setting higher if the quality is still not good enough.

The image resolution looks to be 300x300 dpi at the highest setting, but if the print is very large the image sizes can become very cumbersome at this DPI.

Thanks Ray
I have replied to your email.

Turns out and for future reference nothing to do with the “Intelligent Resolution reduction” but because the transparencies and vectors were clipped together.
Once clipped separately the pixelation of the vector objects is no longer showing.

This is truly very helpful. One of my friends who is designing vehicle wraps for their client had same pixilation issues and sought my help. I am glad that found this post as going to forward it to him and hope this is equally helpful for him.
