When printing with a flatbed printer, there is no need for plate making, sun drying, or repeated color matching. Whether it is a simple block color pattern, full-color pattern, or gradient color pattern, it can be printed in one go. The printing speed is fast, and the finished product is printed after printing. Therefore, tablet printers must undergo pre press testing and sampling before conducting large-scale printing.

　　Pre printing samples on tablet printers can help customers check whether the text, images, colors, and page settings contained in the printed pattern are correct, so as to make timely modifications. Especially in printing, the color of the pattern is the most difficult to control, as different printing materials, inks, and dot gain rates can cause changes in the color of the printed pattern. Therefore, a sample test can be conducted before mass printing to see if the sample color matches the design color, and timely changes can be made before mass printing.

　　Pre printing samples for tablet printers can serve as contract samples between printing manufacturers and customers. The final printing effect must be consistent with the contract sample, and it is best to print the contract sample shortly before the large-scale printing work to avoid sample fading and distortion caused by long storage time.

　　Pre print sampling of tablet printers is an important basis for printing quality control and a tool for communication and exchange with customers. Customers can first print out the samples, discuss the effects, and make modifications before mass production, regardless of what they want to do, what effect they want, and whether they are satisfied. Pre press sampling can reduce disputes between printing manufacturers and customers due to unsatisfactory printing results, saving time and effort.
