7. Requirements to JPEG, TIFF, PSD raster image files
The files shall be carried out in Bitmap, Grayscale, CMYK, Multichannel, Duotone toner modes. Using JPEG compression two factors shall be considered - loss in the quality of image and appearance of artefacts on the images. Files TIFF and PSD must contain only one layer (in Photoshop command Layer>Flatten Image). All unused paths, spot-channels and alpha-channels are to be removed. In the presence of layers with effects in the image there may be a real probability of failure when putting the document on forms or films.
