White stripe when printing 4x6 borderless on Epson R1800

Hi,
Using Gutenprint 5.2 beta 2 on Mac OS X 10.5 to print to Epson Stylus Photo R1800. I've noticed a white stripe on right edge (portrait orientation). This is using 4x6 paper, printing borderless. The stripe is a bit less than 1mm wide, but still very noticeable on borderless print. Another thing is when using "Super Photo" print quality setting (leaving resolution to automatic), which I guess should correspond to Epson's "Best Photo" setting. It looks like dithering is much more visible then with Epson's driver. Also on areas that should be solid color (for example, large areas of sky), the print is very uneven with some visible lines. I did nozzle check, and it seems printer is OK. All in all, using Gutenprint's mid-range "Super Photo" quality setting, the print quality seems to be visibly lower than using Epson's mid-range "Best Photo" setting (I'd say it seems to be even lower than Epson's low "Photo" setting). I'll play a bit more with this in a few days (got a bit low on ink).

I forgot to mention that I was using similar option in the application I was printing from (Aperture, the option is "fill entire page"). The image in question was already scaled for printing to 4x6 and didn't really need any scaling to fit on 4x6 paper. This worked perfectly when using Epson driver (with or without using "fill entire page"). However, with Guttenprint I was getting this white stripe. Using the option you suggested in the driver fixed the problem. However, the Epson driver didn't require any scaling of this particular image to print borderless (the image was from a DSLR camera with 3:2 aspect ratio). I got the same thing with images from two different DSLR cameras (Canon Digital Rebel and Nikon D2X). Do you maybe have a test target I could print on 4x6 paper to check alignment?

When you print it with the Epson driver, does it perfectly fit the page, or are the edges cropped (so that it overprints the edge)? This is all a result of a deliberate design decision that we made -- to give you the choice between preserving dimensions exactly and possibly getting a slight border (or having the image cropped), or preserving what's printed and possibly shrinking or expanding the dimensions. So the default option (shrink if necessary) tries to print the precise imageable area, but does not print full bleed. We can probably collapse the three options (shrink, crop, and expand) into two (resize image to fit printable area, which would shrink or expand as necessary, and preserve dimensions, which would crop if necessary and won't print full bleed). The question is what's going to be less confusing to users. -- Robert Krawitz <rlk@...> Tall Clubs International -- http://www.tall.org/ or 1-888-IM-TALL-2 Member of the League for Programming Freedom -- mail lpf@...

The question is what's going > to be less confusing to users. Last night, I created a simple 4x6 target with 1/32" spaced marks on all 4 sides. The target was created and printed from Google SketchUp LayOut on Mac OS X 10.5. I also made some additional prints of the same target (coverted to PNG using less than perfect screen capture) from Apple Aperture, and those produced same results as printing original directly from LayOut application. I set the expand option in the driver to crop, and enabled borderless option. The result was that on the image printed on Epson Premium Glossy 4x6 paper using Gutenprint driver the leftmost tick was missing, while there was a white space after rightmost thick. In other words, the horizontal alignment was off by about 1mm (give or take few fractions of mm). The vertical alignment was perfect. Looking at the print "portrait" oriented (4" wide, 6" high). Hm, hopefully I haven't put the target upside-down... Now, it could be that the paper feed in my printer got a bit misaligned (factory error? aging?), so it would be great if somebody else could repeat the test on different Epson Stylus Photo R1800 printer to confirm. When using the "expand" option in Gutenprint driver, the image was expanded a bit too much. 3 marks were missing on both top and bottom of the image, 4 were missing on the left edge, and 5 were missing on the right edge. The Epson driver did by default similar thing as Gutenprint with expand option. With Epson driver, 4 marks were missing on the top of the image, 5 on the bottom and 3 on the left and right edges. I've uploaded the original target and the scan of the first print (shrink page option set to crop) to http://sites.google.com/site/amiliv/Home/gutenprint-alignment-targets-for-epson-r1800/. The SketchUp/LayOut apps can be downloaded from http://sketchup.google.com/. BTW, on one of test prints I made, I forgot to enable borderless option. To my surprise, border was present only on 3 sides, while one side was "borderless". Looked kinda strange. Forgot which one (top or bottom), I'll recheck when I get back home this evening. ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

Now, it could be that the paper feed in my printer got a bit misaligned (factory error? aging?), so it would be great if somebody else could repeat the test on different Epson Stylus Photo R1800 printer to confirm. It's also a matter of how my printer might have been aligned (when I set the edge), and how tightly you had the paper against the stop. When using the "expand" option in Gutenprint driver, the image was expanded a bit too much. 3 marks were missing on both top and bottom of the image, 4 were missing on the left edge, and 5 were missing on the right edge. How do you define "too much"? The Epson driver did by default similar thing as Gutenprint with expand option. With Epson driver, 4 marks were missing on the top of the image, 5 on the bottom and 3 on the left and right edges. This is why Gutenprint gives you a choice: you can either get dimensional accuracy and possibly have slight misalignment, or true full bleed and dimensional error. I've uploaded the original target and the scan of the first print (shrink page option set to crop) to http://sites.google.com/site/amiliv/Home/gutenprint-alignment-targets-for-epson-r1800/.

It was tight against the edge. Any more tight, and the paper would bend. When I get home I'll try playing with the printer a bit more and see if I get paper positioned that 1mm more to the left. > When using the "expand" option in Gutenprint driver, the image was > expanded a bit too much. 3 marks were missing on both top and > bottom of the image, 4 were missing on the left edge, and 5 were > missing on the right edge. > > How do you define "too much"? I see now there's two possible definitions for "expand". One would be to expand an image to fit paper of different aspect ratio (for example printing image with aspect ratio of 4:3 on paper with 3:2 aspect ratio such as 4x6"). This would be something I'd expect of "expand" (or "fill") option. In this case it's expanding too much (the marks should fall out of paper only either on top/bottom or left/right margins, not all four). Another would be to expand image to be a bit larger than physical paper, to cover for possible misalignment of paper in the printer. If we use this definition, it is not expanding too much. However, this would be something I'd expect of option called "overprint" or something simmilar. Maybe changing the shrink/expand/crop to fill/crop and separate additional overprint:yes/no option to allow user to select exactly what (s)he wants, similar to what you already suggested, would be a good idea indeed. > The Epson driver did by default similar thing as Gutenprint with > expand option.

Well, there's PNG target file too which produces exactly the same result when printed. You don't really need LayOut application. And there's the scanned print. I guess it should be trivial to create same/similar target in any other drawing program too (it took me about 5 minutes to create this one)... I'm experiencing exactly the same problem visible on the scanned print when printing different images from several applications. It's very consistent. The test target I created is very simple. There should be 8 marks visible on each side when printed on 4x6 paper. Each missing mark means the printer head missed the paper by 1/32 of an inch. If you or somebody else have files I could print to check alignment on different paper sizes, I'll be more than happy to print them out and scan them too. Hmmm... maybe as an idea, to introduce option so that user can adjust edges of the paper in the driver settings (virtually move the paper left/right or top/down)? > BTW, on one of test prints I made, I forgot to enable borderless > option.

I'm cool with that. Though, personally to me, it sounds more logical that setting borderless:no results in borders on all 4 edges.

Yup, and I already started to like this choice. If you or somebody else have files I could print to check alignment on different paper sizes, I'll be more than happy to print them out and scan them too. The CUPS test pattern is one possibility. Hmmm... maybe as an idea, to introduce option so that user can adjust edges of the paper in the driver settings (virtually move the paper left/right or top/down)?

Yup. Exactly like the existing CD Vertical/Horizontal Fine Adjustment options under the Printer Features Extras. Maybe those two options could be changed to allow fine adjustment for any media type (not only CDs). If they are used for what I'm thinking they are used when printing to CDs (never printed onto a CD). Actually, thinking of it, I never attempted to use those two CD options. Would they work as expected when printing to paper too, or are they honored only when printing to CD (mounted in special tray)? ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!

That one is letter format, I had 4x6 in mind. But yeah, it's also one possibility.

There were some visible improvements in output of SuperPhoto setting compared to the beta2. However, the visible lines were still present in the print. Interesting thing is that they always appear towards the top of the paper (looking at the paper with short side up, the way it comes out of the printer). The bottom of the print always looks good. I also noticed on one print a stripe that looks like JPEG artifacts look (it wasn't an JPEG artifact, it just looked like one). The area where I noticed it was part of the sky. There was a small white cloud, and the blue sky to the right of it was garbled, similar to what JPEG artifacts look. The original photo was raw camera file from Nikon DSLR, converted into 16-bit TIFF, and the artifact I mentioned is not visible in it. As before, printing with UltraPhoto settings everything is fine (no lines, no "JPEG artifact"-like stripes). Kind of slow (much slower than Epson driver), but produces very nice prints. If you are interested, I could try scanning the print and putting it somewhere on the web. The "JPEG artifact"-like thing is kind of subtle, and I'm not sure how visible it will be in the scan. I could also mail you the actual print(s) if you want. ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
