Re: [ECI-EN] Fred 15 project-Profile comparision

Hi I have taken 4 test images and separated them using: 1) ISO coated v2 eci 330 2) ISO coated v2 VIGC 320 3) Fogra 51 M0 4) GRACol 2013 CRPC6 I then proofed them on a EFI Fiery XF rip to a Epson 7900, to a Fogra 39 simulation profile to see the visual effects of mixing these profiles in a current Fofra 39 printing condition. Then validated to this condition to ISO 12647/7. The results are interesting. Visually the Fogra 51 and GRACol images are a close match to the two sets of images using the Fogra 39 based profiles. The main area of difference, as may be expected, is in the mid tones. For the Fogra 51 the common CMYK TVI is slightly noticeable. This mid tone difference is also slightly visible with the GRACol CRPC 6 profile which allows for a higher K TVI. I intend to do further tests using differing images which may point to greater differences, but at the moment my first thoughts are that, for most work, images using these profiles may be interchangeable using the differing printing conditions. I also hope later this year to carry out press tests using these profiles and these printing conditions and inter-changing between them.
