Dot size and spacing control how much detail a halftone retains. Resolution adds a second variable: the same pattern can look smooth on a large export and crowded in a small preview.
Test one subject at two sizes
Choose an image with a small detail, such as an eye or a product label. In NexTools Halftone Studio, make a fine-dot version and a coarse-dot version. View both at full size and at the size of a typical card or thumbnail. Note when the detail disappears or individual dots merge.
Adjust for the destination
For a compact social graphic, stronger shapes and fewer dots may be clearer. For a large poster, a finer screen may preserve more shading, provided the output format and print process can reproduce it. Increasing image dimensions alone cannot restore detail lost by an overly coarse screen.
Make a small test export before processing a whole series. Record dot size, canvas dimensions and final display size so related pieces share the same visual texture.
