What problems do yellow rays usually encounter. There is no answer to a question like you. Uneven gelatinization, unclean cleaning, uneven exposure line distance between two sides, etching residue, over etching, endless film stripping, uneven line resistance, etc....... I don't know much about yellow light. Sweet potato is very professional.
