I've recently acquired a used Designjet 5500PS, and am using the UV inks. My hope is to print large format photographs for display or sale. Currently I am trying out HP's quick dry universal glossy photo paper.
My problem is that even when I set the printer options to Max Quality 1200x600 dpi, the image is very pointilized. If I print swatches of color, I don't get a continuous t, but rather a speckled effect. If you look at the print from 3 feet away then it looks fine, but up close it is quite obvious.
Is there any adjustment I can make, either physically to the printer, or through software that will smooth out the speckles?
Thanks for your help!
