Thank you, Gordo and Steve. Herewith some additional info. I am using "bulk stock" to mean the same stock the book will be printed on. The printers we use in Asia have the capability of running our 2 standard stocks (157gsm coated and 140gsm uncoated) on their digital proofers. A couple of our...

For offset printing, is there an industry standard Delta E to determine if the amount of color shift is acceptable? Some scenarios (from children's book publisher perspective) Scenario 1 - Frontlist title 1st printing of a 4C title Received & approved Fuji JetPress proofs on bulk stock In...

Thanks, Gordo. This all makes sense. Too bad SWOP and Idealliance no longer provide those hi-low ink density samples you mention. I completely agree with you that this is something better understood with visual references.

Coming back to this topic as it has come up again at work (I work at a Children's book publisher). After re-reading my OP and all of the replies I realize my wording wasn't clear. The numbers I provided were SIDs (provided to me by one of our Asian printers). What I was wondering is, by using...

Thank you for those PDFs.

Gotcha. Was difficult to interpret your post, at first.

Not sure how that response contributes positively to this thread.

We use printers from all over the globe. The majority of our 4-color work is printed in Asia. Up until about a year ago, we went to a repro-house for wet-proofs (usually 2-3 rounds) before we approved color, and then files were released to the printer (from repro). However, this past year, we...

Thanks for this, Stephen! Do you know if they have made updated profiles to go along with Fogra 51? I'll poke around to see what I can find but perhaps you know.

What I'm trying to achieve is a way to communicate to designers what the allowable color shift throughout a given print run may be, and I'm trying to do this in a way that they will understand. If I bring up SID, LAB, or Delta E they are just going to immediately tune out. If i was able to...

For anyone working on a press, or in Prepress, what, if anything, do you do to compensate for the color shift when applying matte lam? I work for a publisher and for years I have always added a Curve to jacket/cover art that would take down the M by a touch (approx 2% from the midtones) and Y...

Looking for advice on how to explain to designers that we (the customer) have to accept some variance in color which is within industry standard tolerance. What is the best way to do that. If I was to show them this, it would do no good: Coated Stock C 1.45(+/-0.08) M 1.40(+/-0.08) Y...

My company has recently started receiving more and more Epson proofs, in place of wet-proofs. For 4-color interiors we are seeing double-sided Epson proofs (forms). I never realized Epson proofs could be double-sided. Are any Epson printers capable of this straight out of the box, or is...

Thanks, Magnus!

Hi, Steve. Can you help me with something in regard to Epson proofs. Please see the attached photo of an Epson proof we recently received. Notice the 2 different whites. The outer white (the cleaner white) I assume to be the actual color of the stock. The inner white (what is looking a bit warm)...

For the titles we print in the states (mostly 1C fiction titles) we do receive Epsons for the jackets/covers. Overall feeling in regard to the Epsons is they are flat/dull and any lamination compensation curve applied is usually not accurate.

Hi, We're in the process of pitching the idea of ditching wet-proofs (especially for digitally created artwork) and getting digital proofs, instead. I've poked around on this site and online, in general, but I am unable to find a concise breakdown on the different types of digital proofs...

Got some feedback from the Repro House, which seems to me more in line with what folks here are stating. Response from Repro: "Frankly, we believe ISO 12647 did not really specify the ink density, but specified the Lab value for the CMYK ink. However, we agree the ink density could provides a...

Thanks, Steve. Will ask that question next.

Overnight, I confirmed with this specific printer that their ink sequence is KCMY. Our main repro house has recently switched to CMKY - using 2 separate 2-color presses to produce their wet-proofs. Am I correct in thinking the difference in ink sequencing would make it near impossible to match...
