Send the differences between your own preflight tool and Seshat as a second reading. Rekhu keeps them for review, and only a reviewed difference teaches anything.
Read more →Seshat 1.8.1 converts RGB, Lab and spot colours to CMYK with overprint, spot plates, rendering intents and the file's own output intent kept, and prints every patch of the Ghent PDF Output Suite 5.0 test pages as separated.
Read more →Seshat 1.8.2 reports white overprint only where white really vanishes on press, reduces total ink in gradients and DeviceN colours too, and stops taking colour values for phone numbers.
Read more →Seshat 1.8.3 measures the highest ink over any area of about a millimetre inside the printed area, counts registration colour used as content, and turns it into black while printer's marks keep it.
Read more →Seshat 1.8.4 measures total ink from the separated page with every printing ink, CMYK and spot colours, so the check and the plates always show the same number.
Read more →Seshat 1.8.5 reuses the check made just before a fix and measures ink once, so a fix after a check takes about a third of the time.
Read more →Seshat 1.9.0 checks files against the values the Ghent Workgroup publishes for each kind of print, measures total ink as the GWG specification does, and finds content in the registration colour.
Read more →Seshat 1.9.1 brings total ink under the limit with grey component replacement, so colours keep their look, and draws a heat map of where the ink is too heavy.
Read more →Every fix answers whether it changed the file, empty bleed and white set to overprint are found, RGB black prints on the black plate only, and RGB findings say where the RGB is.
Read more →Send the folds of a folder and Seshat reports text near a fold, barcodes whose quiet zone a fold touches, faces cut by a fold and small logos a fold runs through.
Read more →Seshat keeps text clear of folds by at least the ISO 16763 folding tolerance, reports white that vanishes in Multiply, reads colours inside patterns, and fixes that change nothing when run twice.
Read more →Seshat, Rekhu's preflight for print files, now has a product page with what it checks, the standards behind it and its prices, and checks a file from the command line with no code.
