Embodiment Construction

[0012] Such as figure 1 As shown, the present invention includes an observation platform table top 2 arranged on a stand 1, a standard light source 3 is provided directly above the table top 2, and a vertical panel 4 is provided on the back of the observation platform, and the surface of the vertical panel 4 is silver or White, so that the table top 2 of the observation platform obtains the reflected light of the light source, making the observation atmosphere more in line with the actual natural light.

[0013] The standard light source 3 in this embodiment is fixed above the table top 2 of the observation platform through two vertical telescopic rods 5 , and the light source just shines on the table top 2 . Adjust the telescopic rod 5 so as to adapt to the reflective intensity of different product surfaces and reduce the chance of distortion.

[0014] In order to facilitate observation, the table top 2 of the observation platform in this embodiment forms an angle of 20-40 d...

Abstract

The invention provides a printed product color observation desk comprising an observation desk board arranged on a bench. A standard light source is arranged right above the desk board. A vertical panel is arranged on the back of the observation desk. The standard light source is fixed above the observation desk through two vertical telescopic rods. The observation desk board and the horizontal plane form an included angle of 10-30 degrees. A locker is arranged under the observation desk. The bottom of the observation desk board is provided with a raised horizontal stopping bar. According to the invention, the standard light source is provided to ensure that the product surface basically has no chromatic aberration under natural light, a good test basis is provided, there is no error in the observation, contrast or color matching result, and effective supervision on the quality of products is realized. By adjusting the telescopic rods, the distance between the light source and a product can be adjusted so an accurate result is obtained. The stopping bar at the bottom of the observation desk can ensure that products do not slip off in observation.

Description

technical field [0001] The invention relates to printing inspection equipment, in particular to a printed product color observation table. Background technique [0002] Packaging products in the flexible packaging industry generally need to be printed, and printed products have problems of hue and color difference. In the past, we only installed an ordinary single fluorescent light source in the workshop, and the color temperature was different from the national standard, which caused a certain color difference to the product. In addition, under different light sources, the color of the object has a metamerism effect, which produces different visual effects, thereby affecting the judgment of the human eye on the color. In order to ensure the quality of printed matter, in the process of proofing or printing, it is necessary to observe the color of the printed product at any time, and compare it with the color of the original or proof. The printing site often does not have a ...
