It&#8217;s only meaningful if the monitor itself is calibrated and the viewing conditions are controlled \u2014 otherwise, what someone sees on screen has no reliable relationship to what will come off the press. ISO 12646 is the international standard that defines exactly what a display needs to meet \u2014 chromaticity, luminance, uniformity, and the surrounding ambient light \u2014 for a soft proof to be considered trustworthy, with two conformance levels, Class A and Class B, covering different levels of rigor.<\/p><p class=\"wp-block-paragraph\">This matters directly for DAM-based approval workflows, which increasingly happen entirely through a browser preview rather than a printed proof passed around a room. A stakeholder clicking approve on a color-critical asset inside the DAM interface is implicitly soft proofing, whether anyone calls it that or not \u2014 and if their screen isn&#8217;t calibrated to anything close to ISO 12646, that approval isn&#8217;t a reliable signal that the printed result will match.<\/p><p class=\"wp-block-paragraph\">None of this means every DAM approval needs a color-calibrated monitor \u2014 for most day-to-day marketing assets it doesn&#8217;t matter. It matters specifically for color-critical print work: packaging, brand color-sensitive collateral, anything where a visible shift between the approved screen version and the printed piece is a real cost. For those cases, the DAM approval step should be flagged as requiring proper soft-proofing conditions, or backed up with a physical hard-copy proof before the press run is committed.<\/p><p class=\"wp-block-paragraph\">ISO 12646 evaluates a display across several dimensions before a soft proof can be trusted:<\/p><ul class=\"wp-block-list\"><li>Chromaticity \u2014 color accuracy of the display<\/li><li>Luminance \u2014 brightness level and consistency<\/li><li>Screen uniformity \u2014 no drift between edges and center<\/li><li>Ambient light in the viewing environment<\/li><\/ul>","protected":false},"excerpt":{"rendered":"<p>Soft proofing is reviewing how a print job will look on a calibrated, standards-compliant monitor before committing to a physical hard-copy proof or a press run.<\/p>\n","protected":false},"author":0,"featured_media":0,"template":"","meta":{"footnotes":"","faq":[{"question":"What's the difference between soft proofing and hard proofing?","answer":"Soft proofing reviews color on a calibrated monitor; hard proofing produces an actual printed sample on the intended (or a proofing) substrate.
