<p>I plan to print a Photo book with b/w pictures in offset, using CMYK printing.</p> <p>When preparing the pictures for print, I am proofing them in Photoshop, using the Fogra 39 Soft Proof Profile, taking care to have the "Simulate Paper Color" checked.<br> In addition, I would like to make Hard Proofs with my Epson 3880 printer, using the Hard Proof Facility of Photoshop CC. Photoshop provides for this in the Print Dialogue. </p> <p>In the Print Dialogue I first chose "Photoshop Manages Color"; then I enter, under PRINTER PROFILE. the profile for my paper (Baryta Photographique) "cifa_3880_baryta310_p_bk.icc". Finally i chose "Hard Proofing" and enter, under PROOF SETUP "Custom set-up". Therein i put "Coated Fogra 39"; "Relative Colorimetric"; and "Simulate Paper Color".</p> <p>When I am printing with this configuration, the result is, to my surprise, the same as if I had printed normally, choosing "Normal Printing" instead of "Hard Proofing". This is in clear contrast to the screen, where the soft proof shows a sizable difference in contrast to the unproofed picture. </p> <p>Is there a bug in Photoshp CC, preventing me from Hard proofing? Permit me to add that I have also checked SEND 16-BIT DATA, but that should not have any influence on the hard proofing.</p>
