To confirm sample is passed to the printing service provider or printers of the same electronic file.
If the page is too large to print the same as the actual size of the original sample, be sure to mark shrink ratio on the sample. Color printing should live on the laser printer print out color separation proof (in the form of black and white). In addition to the color proof to the printers, you should also provide color sample, sure each color separation proof is correctly marked with the color. And check the color sample color is correct and the chromatic number of color separation. If the offer is black and white and synthetic sample, should be clearly marked with different color printing parts.
