The process of offset plate copy is controlled through the correct reproduction at the highest and the lowest tone. We propose that we should control the whole tone, and we need the correct control method. Based on the offset control strap, this paper proposes a new detected method of plate resolution and analytic method of the correct copy range of plate. Using these methods and through the experiment,...
The colorimetric evaluation methods for ink trapping are put forward in this paper. The first is based on ideal overprint of inks. The other is based on the psychological chroma of ink colors. After the computational method and process obtained ink trapping values through several evaluating methods were discussed and analyzed, the following results were given. The densitometric evaluation method for...
