Since there doesn’t seem to be much of a difference in image quality between the 2880/1440 dpi and the 1440/720 dpi settings on the Epson 3880 driver, I’m confused about why both exist. Having three different ink drop sizes in 1440/720 mode results in print times about half of those printed with the higher-resolution setting,… [Read More]
iPhone 4 for Verizon OOBE
The packaging is just as Applelegant as usual, but it’s less user-hostile than before. It was easy to figure out how to open it up, find all the bits, and get it running. At no time did I have to pull out a magnifying glass to see how to open a plastic case, and I never felt… [Read More]
Does dot resolution influence smoothness?
From the mailbag: …I didn’t see anything mentioned about variable droplet sizes. With 2880 you’re always using the smallest size droplet…where as with 1440 you are getting a mixture of large, medium, and small droplets. So sometimes 1440 can look smoother because of the way these various sized droplets “fit” together. Or that was the… [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]
