Description

Technical Field

[0001] The utility model relates to the technical field of printing detection, in particular to a printing product viewing platform with an adjustable platform. Background Art

[0002] In the field of printing alignment, in order to ensure the quality of printed products, it is necessary to observe the color of the printed products at any time during the proofing and printing process, and compare the finished products with samples or originals. Under different light sources, the colors of objects will show metamerism effects, resulting in different visual effects, which will affect the human eye's judgment of color. In industrial printing, in order to avoid the above-mentioned effects, a printing sample viewing table is generally used for observation and comparison; the printing sample viewing table refers to a printing detection device that provides a standard light source for the color detection of printed products, so as to avoid color distortion of printed products and improve the accuracy of color detection of printed products.

[0003] At present, the existing utility model with publication number CN202177453U discloses a printed material viewing table, including a standard light source, a viewing table and a bracket. The viewing table is arranged on the bracket, and the standard light source is arranged above the viewing table through a vertical plate.

[0004] In the above scheme, the standard light source in the prior art is fixed on the upper end of the vertical plate, and the finished product and the control sample are placed on the viewing table for observation. However, in actual use, the reflection intensity of different printed materials is different. Changes in pattern lines, color, and surface flatness on the surface of the printed material will affect the reflection intensity. Therefore, during observation, the difference in reflection intensity will affect the human eye's recognition of the color and pattern of the printed material, affect the detection effect, and cause inaccurate detection problems, which need to be improved.
