2. EXTERNAL FILES

If the client's file uses images or objects, generated in another program, no matter whether they are embedded or externally linked, these images or objects have to be supplied together with the file. If the client encloses DCS EPS files, they must be saved with ASCII encoding. It's not allowed to transfer images between different programs using the Clipboard (PC and Macintosh). For such purpose the commands / or in the programs must be used.

3. FONTS

The client must bring the fonts that are used in his files, except the case when all texts are converted to curves. It's recommended to use only PostScript® Type1 fonts. If Windows® system fonts or TrueType fonts are used, then the executor does not guarantee the exact reproduction of the originals.

4. PRINTINGS

Every file that is received for pre-press work must be attended with actual printed copy of the pages. If these are missing they will be made in Dunav Press at client's expense with the purpose of keeping the quality requirements.

5. COLOURS

All colours in the Pantone® system and these defined as SPOT-colors will be exposed on a different color separated films. If colors defined in RGB, HSB and Lab system are used in client's files, then the standard methods and profiles of Dunav Press will be applied for conversion to CMYK and color separation. If any profiles are embedded in the client's file, then the exposure will be made by their use.

6. TRAPPING

The parameters of the trapping and overprinting of the colors must be set for every single object in the documents.

7. MISCELLANEOUS

If some additional modules (plug-ins) are used for file generation, they must be brought together with the working file.

The maximum number of the points or junctions in a vector image is limited to 500. The same number is used as a limitation of the clipping paths in Photoshop EPS files.

The final size of the product is determined by the document's size and the additional specific fields that are necessary for the printing process. Thus it's recommended to contact a technology dispatcher in Dunav Press for determining the desired size of the product.
