Define the card’s purpose first
A fan deck helps narrow existing variants. A coated spray-out card shows the result of a selected mix and actual application. A reference does not automatically replace your own sample.
Define whether you are comparing formulas, checking an intended substrate or documenting a mix. This determines which substrate properties matter.
Specific examples from manufacturer research
Colad describes paper cards 9310 with black-and-white control areas and a comparison hole; the control area indicates coverage. Other examples include coated paper series 9314 and metal series 9319.
These show different materials and versions, not a universal ranking. Check the chosen card’s own manufacturer information. They are external technical examples, not promised BUWO accessories.
Compare ground colour and material separately
Record both the intended ground colour and substrate material. Changing these together with application makes differences harder to interpret. Compare deliberately defined samples rather than random leftover cards.
A coated card should not be reused merely because space remains. Preparation and any permitted reuse follow the card and coating-system documents.
Coordinate format and mounting
The format must fit its intended holder. Check fixing, access and handling after coating. A card manufacturer’s holder is not automatically included with the BUWO station.
Provide dimensions, material and a photograph when enquiring. Alongside the device and intended method, these identify compatibility questions still needing confirmation.
