Hi;
I started playing around with a canon Pixma 8750 Printer; to hang some prints at home and give to family members. The first print I tried to make was for an old frame I have and want to keep: 395 x 300 mm.
I put the image through soft proofing (made a rookie mistake there) and then ran the printer setup: Fed it an A3+ paper (Super A3) and in my print-module I set it the cell height to 39,5CM and the width to 30. I take the Margins all the way down to the lowest value and press print.
The print comes out, too red and too big 304mm wide and 399mm high. The color problem I figured out, I had to tick the 'color/intensity Manual adjustment' box in the setup of the printer (at least I think, will get myself some 10x15s of the same paper to test).
When reviewing my settings I noticed I had the option 'borderless printing' ticked too. When hovering over there it says the image will be enlarged slightly to create a borderless print. Is this the cause of my problem? I'd assume the printer/lightroom/computer is smart enough to realize I'm printing an image at an expected size on a paper that is 'too big' anyway (so there will be a border whatever you do) and then overrule that setting?
Flickr is a great platform to begin with and you can use the Flickr storage as a backend for your own website. It's not as fast as using an image CDN, but the speed difference is not that noticeable.
