Title: Printing Resolution + Interpolation method Post by: Jejes on June 24, 2025, 06:06:25 PM Hello i'm printing with Canon4000XPS in 16bit driver mode and i know the driver accepts images in 600dpi. My images are in 300 ppp and when i print i set Print Resolution to 600 and Interpolation to Forge. When i set this i get a small banding like when i get a clog. But if i print all to OFF i get perfect images. How i should print to get rid of the banding and printing to 600 ppp. I would like to use the interpolation from Qimage.
What i'm missing ?

It offers no benefit and has bugs so just switch to the regular driver.

But I have this problem, could be it related to pronto to 600ppp and image that is 300ppp. I’m enlarging in image and maybe it generates banding in solid colours. Sending the image with off (300) I have no problems resizing to 600ppp it gives me banding.
Thank you Title: Re: Printing Resolution + Interpolation method Post by: admin on June 26, 2025, 03:42:38 PM The problem is the XPS driver: it has many issues. The XPS driver is only 16 bit for Canon software so it is useless (and buggy) for anything else including Photoshop, Lightroom, Affinity, etc. because the driver pipeline in Windows is 8 bits. Qimage already does 16 bit printing via any driver including 8 bit drivers so there will be no difference in quality.
Bottom line, don't use the XPS driver and instead use the normal non-XPS driver. Regards, Mike |
