How to prepare a file for printing coasters/wafers?
Project sizes
The project should be prepared according to the selected template available in the calculator after choosing a specific coaster design/size.
The die-cut templates are available in the D&D database and do not need to be attached to the submitted files.
Do not change the proportions, dimensions, or layout of the provided template.
Preparing the artwork
The finished project should be prepared as a multi-page PDF file (single- or double-sided print design).
The print area depends on the coaster design. All essential elements of the project, such as texts, logos, and important graphic elements, should be placed at least 5mm away from the edge of the finished product.
Backgrounds and graphics extending to the edge should be prepared with a 2 mm bleed,
Note
Due to the specific nature of panka board and production tolerances, slight shifts between the front and back print may occur. Therefore, it is not recommended to design frames or borders, as even a shift of +/-1.5mm can affect the final result.
Color settings
The project should be prepared in the CMYK color space.
Do not leave elements in RGB color space, as their conversion to CMYK may result in color shifts.
The total CMYK components in the project should not exceed 200%, unless a test has been performed beforehand.
Excessive ink coverage may cause improper drying, ink bleeding, and loss of edge sharpness in prints or fine elements. Therefore, avoid large areas of color, such as tints and solid fills.
If you want intense, vivid colors, build them from one or two CMYK components with the highest possible saturation. Adding a third component or black usually reduces color intensity on absorbent substrates.
For example, intense red is best defined as:
C: 0% / M: 100% / Y: 100% / K: 0%
Black color
Black for texts, thin elements, and other black objects should be prepared as 100% K only, without additional components
C: 0% / M: 0% / Y: 0% / K: 100%
Raster graphics and photos
Raster graphics, photos, and bitmaps should have a resolution of at least 300 dpi.
Enlarging graphics with too low a resolution does not improve their quality and may cause visible pixelation or loss of sharpness in print.
Texts and vector elements
Logos, texts, QR codes, and barcodes are best prepared as vector elements.
All texts should be converted to outlines.
QR codes and barcodes
Codes should be black 100% K on a light background. QR requires a clear margin, the so-called quiet zone, of at least 4 modules on each side.
Color reproduction and substrate influence
Printing is done without the use of white ink. The absorbency of Panka board and its off-white/ecru color affect the final appearance of the print. A monitor emits light, while cardboard reflects it. Therefore, even a correctly prepared project may look slightly different on screen than on the finished coaster.
For projects where color is crucial, the best way to assess the result is to order a prototype for 1 PLN. https://n.dd.com.pl/podkladki-wafle-piwo-napoje
