No. We print your file centered on the sheet. Please do notplace the white border in your file, only the print area. The white border results.
Example: Print area (delivered file is e.g. a landscape format) is 30.0 cm x 45.0 cm. Printed on an A3+ sheet (paper size 32.9 cm x 48.3 cm), the theoretical margin is 1.45 cm top/bottom and 1.65 cm left/right. In fact, however, there is a technically determined size and parallelism tolerance of up to 2 mm measured to the paper edge for the margins.
