To prevent fine dots from vanishing in light areas, begin with a comprehensive print test sheet covering a 0 to 5 percent gradient range. Use the Ugra Plate Control Wedge standard as a benchmark and examine at least 500 individual dots under controlled conditions. Measure each dot’s stability with an X-Rite eXact spectrophotometer and record the lowest percentage that consistently prints without dropout. This value becomes the operational Minimum Dot for the press and substrate combination.

Apply this calibrated Minimum Dot in prepress software such as Esko to adjust tone value increase curves accurately. The updated curves compensate for dot gain and ensure smooth transitions in highlight regions. This method eliminates highlight breakup in packaging graphics and maintains visual consistency across large print runs.
