From time to time the issue of gloss level surfaces, usually when a comparison is made between a colour card with a flat finish and a sample with a high gloss. It is very important that you have system in place for keeping accurate records of formulations you have supplied to your customers. Some specialty products are formulated with unusual levels of TiO2 or pigmentation. These do not fit exactly into the standard tinting system. Changes in tinter amounts are required to tint these products to produce standard colours.
Care is required to ensure opacity and avoid exceeding the tint limits.
Exceeding the tint limits can cause some long term problems, especially with some higher performance products. These colours are transparent or semi-transparent inks and much of their brightness is due to the white background showing through. Paint, however, is an opaque medium and it is rarely possible to match the brighter colours. A colour chosen off an existing range satisfies most customers Speciality Matches Colour matches to cloth or reflective surfaces such as anodised aluminium or pearlescent papers are usually what we refer to as subjective matches. With these surfaces, the colour seen depends on the angle from which the surface is viewed and the lighting conditions, and the customer is generally unaware of this.
