The objective of this and other analyses is to accurately measure the performance of all press equipment to allow any variations to be identified and remedied immediately. By continually narrowing the tolerances accepted in our equipment, we strive to constantly improve the quality and consistency of our work. Vertex Printers has a compliment of 5 Sheet-fed presses from 19_ to 30_. For development of special shades our in-house facilities include mixing custom colours using top of the line spectrophotometeres to measure colour in three dimensions including new Pantone Formula Scale guaranteeing accurate colour matching. For the custom shades to be used on regular basis, we have a contract with Coats Pakistan Ltd. (A joint venture of Coats Japan and Packages Ltd. producing printing inks) who would produce any special shade for us even in the minimum quantity of two kilograms.
