Sometimes it is necessary to order a new banner, poster or sign next to the previous one or to display products printed on different materials side by side. Of course, in such a situation, every customer wants the colours to look exactly the same.
In digital printing, the colour tone depends on several factors, first of all the material. The colours on PVC and board are brighter than on a mesh with holes, colours on textile fall in between of them. The white colour of the materials in the different batches may be slightly yellower in some, greyish in others, bluish in thirds, although they all are white. The colour tone also depends on the specific printer and the inks from different manufacturers that are used for printing.
The first tip for digital printing is to make sure the design file is in CMYK colours, because that's what digital printing uses. For RGB tones, we need to convert it to CMYK first, and inaccuracies may start from there.
Another tip is to include a Pantone colour code with your order. This is the case in one of the above situations (two posters produced at different times or on different materials side by side, etc.). This allows our printer operators to manually adjust the colour distribution to achieve the exact result needed. The existence of the Pantone code allows us to be informed at every stage, to check the colour tone and to target it as close as possible, even if there is no direct reference moment with another product.
In summary, make sure that the colours in the theme file are CMYK tones, and include the Pantone colour code if you want a very specific result.
