What's needed for production

Logo on final product

The technical requirements differ between imprint methods. Most techniques require lossless logo resizing which demands a vector-based image format. Raster based printing may also use raster images in some special cases. The most used format used in transfer to suppliers is
EPS / vectorized.

The implemented color scheme/model also depends upon the imprint method. For printing on paper mostly CMYK is used. For other surfaces PANTONE is preferred; In some cases HKS is possible.

All other color schemes and models like RGB, HSL etc. are generally insufficient for printing. There are exceptions, for example grayscale laser engraving which is capable of processing RGB images (with certain suppliers).

Logo on digital ads

Using online ad formats such as Google Ads or the digital agency-provided newsletters need automatic creation of realistic looking proofs.

The underlying processes use raster image based toolsets (mainly ImageMagick). This requires logo files with these properties:

• Large enough to be scaled
• Small enough to be processed in reasonable time / with reasonable costs
• Anti-aliased alpha channel: All that's not the logo has to appear fully transparent.

The resulting definition is:

• PNG image with alpha channel
• Defined minimum pixel size of longest side

Color information

Digital ads creation needs to match product images with logo colors. Logo and product colors have to exist in a comparable format.

Definitions for color matching:

• HSV color scheme/model
• Pre-processed images for colour clustering
