The solution offered was for Office 2007. The solution pointed to by Kelly on Microsoft’s website appears to resolve these problems including the RGB grayscale image problem. Thus, the PostScript grayscale correction output feature of Acrobat X / Reader X is defeated for such imagery. However, to some degree with Office 2007 and especially with Office 2010, the image compression used “ruins” such RGB grayscale images such that it is no longer true that for every pixel, R=G=B. ![]() This eliminates the undesirable color casts and unexpected color print click charges. A new feature of Acrobat X and Reader X by default (except for PDF/X files) automatically intercepts any R=G=B text, vector, smooth shades, and raster images and for PostScript printing, outputs these as CMYK=(0,0,0,K), effectively true grayscale. Such rich black / gray not only can look terrible in terms of unexpected color casts, but also can cause “smart” printing devices that have different “click charges” based on whether a page is fully monochrome or not to register as a color page. Although in theory, such raster images would output as grayscale or effectively CMYK=(0,0,0,K), in fact ICC color management doesn’t quite work that way and such images will print out either directly from Office applications or from PDF created by Office with rich black / gray. Many images in the enterprise / office environment are like this. RGB grayscale images? What are they? Very often, especially in non-graphic arts environments, what you think are grayscale images are really RGB images in which for every pixel the R, G, and B values match (i.e., R=G=B). (2) The other problem that has been seen is associated with RGB grayscale images. (1) Obviously, the unexpected downsampling of images itself can eliminate or fuzz out detail in a raster image. They also occur and are even worse with Office 2010! The manifestations are two-fold: The problems associated with raster image compression and degradation cited by Kelly above are not limited to Office 2007. "You can also modify the following registry setting to prevent basic compression from occurring by default." Note: Clicking OK on this dialog will not prevent the issue from occurring. In the Compress Pictures dialog box, click Cancel. Click to clear the Automatically perform basic compression on save check box.Ħ. Click Tools, and then click Compress Pictures.Ĥ. Click the Office Button, and then click Save As.Ģ. "For future saves, compression can be disabled on a per-file basis using the following steps:"ġ. "It is not possible to recover pictures that have already been compressed." ![]() "This issue occurs because PowerPoint, Excel, and Word perform a basic compression of images on save." On the quality issue, Microsoft has a tech note that may help resolve the issue: For Line Art images, changing the downsampling to Average is also another good setting, to prevent the anti-aliasing halo that works well for photographs, but not for drawings. That will give you less image compression and higher resolution. Office 2007 uses a new graphic engine for handling pictures and we've seen complaints when images were placed and scaled down (which is the opposite of what should happen, scaling down typically improves image quality).Īlso, I recommend you change your PDF settings to High Quality print. I realize this is an older post, but I wanted to offer some information that may help. ![]()
