Generally, the CDS imported are PSD and TIF images. Except for the PSD file with unmerged layers which can be recognized through attributes after import, the other three types of images, namely (1) merged PSD, (2) unmerged TIF, and (3) merged TIF files, cannot be distinguished after being imported into the CD.
If the imported PSD image is rotated, mirrored, resized, tilted or subjected to other actions on the CD, it is very likely to be broken during the output process. Therefore, for the imported image on the CD, if it has undergone rotation or other actions, it is safest to convert it to a bitmap. When precisely cropping the bitmap within the image frame, the above issues should also be noted. At the same time, it is necessary to check whether the frame is locked with the image. If not, please lock it.
Based on the above analysis, the processing methods before image typesetting can be summarized as follows, totaling five points:
1. Images and images with shadows only need to be converted into bitmaps after rotation, mirroring, and tilting actions have been applied.
2. Images with different resolution values in the attribute information need to be converted to bitmaps.
3. The images in the precise cropping box that have been rotated or have different resolutions must all be converted into bitmaps.
4. For RGB images, except for the bitmap conversion in the above situations, you can directly convert them to CMYK mode (do not select all RGB images and convert them together, as the images may not be on the same layer, and some strange problems may occur after conversion).
5. Images with filters need to be converted into bitmaps (Note: Whether the changes in the original image after conversion are too large).
6. Regarding masks, be cautious when using them in coreldraw. When necessary, it's safer to use the "insert into container" method.
