Printing Formats
There are two prevalent printing formats in use today: 傳統膠印和數碼印刷.
Traditional Offset Printing
The workflow of traditional offset printing involves plate production (利用四色板) 將潤版液和油墨塗到印版上. The ink is then transferred from the plate to a rubber blanket and ultimately imprinted onto the paper through a process of lithographic pressure, resulting in ink transfer.
Throughout the production process, which encompasses various intermediate stages, the printed material is considered an indirect output.
The most commonly encountered machine for traditional offset printing, particularly in the market, is the Heidelberg printing press, renowned for its four-color capabilities.
Special Edition Printing and Imposition Printing are two different printing methods.
Imposition printing refers to the process of combining multiple files onto a single printing plate. 例如, in the case of a two-page spread, it can accommodate eight 16-page layouts or over 100 business card positions. The advantages of imposition printing are its relatively lower cost. 然而, it has limitations in terms of available printing techniques, subpar color quality, and potential insufficiency in quantity to meet demands.
Special edition printing, on the other hand, involves using separate printing plates for each file. Each file has its dedicated printing plate. The advantages of special edition printing lie in ensuring color accuracy and an ample supply of quantities. 然而, the price of special edition printing is relatively higher, especially for smaller quantities.
Digital printing is commonly used for printing materials with low print quantities or those requiring special paper. Due to its simplified process and less complexity compared to traditional printing machines, digital printing machines are often chosen when quick printing is needed.
