I went to mount a 17x25 print this past week. When I went to cut the matt, I noticed the print was significantly off. So today I took much more care and tried printing again.
I'm using an iMac, Epson P800, El Capitan and Lightroom 6.9. The paper is Red River 68lb UltraPro Satin 4.0 17x25. The actual size of the printed image is 16x18 1/2. This equates to 3 1/4" margins on the vertical and 1/2" margins on the horizontal.
When I used the rear feeder, the horizontal margins are skewed a little more 1/16" which is noticeable. One odd thing is only the two corners on the right side of the image are off. The two corners on the left side are perfect.
When I use the front, fine art feed, the horizontal margins of all four corners are a little less than 1/32" which is more than acceptable.
So I'm wondering, has anybody else noticed this? Is the front feeder by nature more accurate than the rear? When I loaded the rear feeder, I only used one sheet of paper; should I have used more? Or, is 1/16+" acceptable and I should just stop worrying?
