anon1 Posted April 6, 2017 Share Posted April 6, 2017 (edited) http://www.color.org/WP40-Black_Point_Compensation_2010-07-27.pdf (examples at the end) http://www.color.org/AdobeBPC.pdf "Although ICC profiles specify how to convert the lightest level of white from the source device to the destination device, the profiles do not specify how black should be converted. The user observes the effect of this missing functionality in ICC profiles when a detailed black or dark space in an image is transformed into an undifferentiated black or dark space in the converted image. The detail in dark regions (called the shadow section) of the image can be lost in standard color conversion. Adobe Systems implemented BPC to address this conversion problem by adjusting for differences between the darkest level of black achievable on one device and the darkest level of black achievable on another. Because BPC is an optional feature that the user can enable or disable when converting an image, the user can always decide whether the conversion of a particular image looks better with or without BPC. " TLDR: on because otherwise the shadows get crushed (sometimes the printing company also tells you how to set up) maybe helpful in general: https://forum.affinity.serif.com/index.php?/topic/33820-color-profiles-management/?p=165094 https://forum.affinity.serif.com/index.php?/topic/32516-soft-proof-in-practice/?p=158109 Edited April 6, 2017 by MBd Quote Link to comment Share on other sites More sharing options...
affwin Posted April 7, 2017 Author Share Posted April 7, 2017 Hi MBd, thanks for the info. The color management is already familiar to me with the "many" profiles, but the BPC I had not heard so far. Since I use with my printer always perziptiv, BPC is always switched on automatically.But it will be tested in the Softproof if a difference is visible (as in the example pictures). And for Germans like me in German -> http://fotovideotec.de/farbmanagement/10_kontrastumfang.htmlGreeting Dieter Quote Germany, Affinity Photo WIN 1.7 , LR6, WIN10 Link to comment Share on other sites More sharing options...
