Four or five months ago, I did a series of posts on resampling for printing. You can read the summary here. Since then, a new version of Qimage has been introduced. It has a new algorithm, called “Fusion”, which is supposed to give better results than the “hybrid” algorithm. Also, there is been a new… [Read More]

More on Epson driver resampling
Warning. What follows is probably only of interest to the technically obsessed. In the last post I showed examples of printing a 720 ppi target with the Epson 3880 driver set to various options to prove that the “Finest Detail” checkbox controls whether the image is resampled to 360 ppi or 720 ppi. Interpreting the results means deciding whether the printer… [Read More]
Controlling resampling in the Epson driver
From the mailbag: Jim, I’ve been told that the Finest Detail feature applies to vector art/line art only. That it has no effect on bitmapped images at all. I gather your result contradicts that assertion? I’ve never done systematic testing of it. My tests with V- and H-stripes test images showed clearly (a few years back) that… [Read More]
Triggering resampling to 720 ppi
Through a combination of research and further experimentation, I’ve figured out that checking the “Finest Detail” option box in the Epson 3880 driver is the thing that tells it to resample the image at 720 ppi instead of 360 ppi. The 2880/1440 resolution setting tells the halftoning algorithm not to use any but the smallest… [Read More]
Resampling for printing – summary
Have you been looking at the last couple of weeks’ posts and been wondering what to make of it all? So have I. Here’s what I think: The marking engine (printer engineering talk for the collection of parts that lays down the ink, or toner, or whatever) of the Epson 3880 is capable of consistent… [Read More]
