Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of printed matter processing, specifically relates to a printed matter color difference detection device. BACKGROUND

[0002] A printing press is a device used to transfer text, images, or other designs onto paper or other materials. It is widely used in the publishing, packaging, and advertising industries, and can efficiently produce books, magazines, newspapers, and various types of labels and packaging.

[0003] Printed matter color difference detection is an important process for evaluating and ensuring the color consistency and quality of printed products. It involves using professional equipment to measure the color of the actual printed result and comparing it with the expected standard (such as design files or samples) to identify any deviations.

[0004] As shown in a Chinese public patent with patent number CN221602597U, the cited document includes a conveying mechanism, and a statistical mechanism is fixedly connected to one end of the upper surface of the conveying mechanism. The statistical mechanism includes a quantity counter and a display screen, the display screen is inlaidly connected to one side surface of the quantity counter, and mounting seats are fixedly connected to the lower middle parts of the two side surfaces of the quantity counter. A scanning piece is fixedly connected to the bottom surface of the quantity counter, and a pushing mechanism is fixedly connected to one side end of the upper surface of the conveying mechanism. The statistical mechanism and the rejection mechanism provided in the document solve the problem of the single function of the existing printed matter color difference detection device.

[0005] The above-mentioned cited patent, although it realizes color difference detection of printed matter and rejection of defective products, still has certain use limitations in use, i.e., the color difference detection camera in the document is fixedly arranged on the supporting mechanism, and the color difference detection height is limited by the installation height of the supporting mechanism in actual color difference detection. If the distance between the camera and the measured object is fixed, and the target surface shape of the printed matter is different (such as concave-convex, curved, etc.), the uniformity of light reflection may be affected, resulting in deviation of the color data collection result. At the same time, color difference detection at a fixed height is easily disturbed by environmental factors (such as changes in light angle), and the consistency between different batches is difficult to guarantee, which has a negative impact on quality control. In addition, when the printed matter is not completely dried, the color difference detection camera arranged at a fixed height is prone to further color difference measurement errors. Therefore, a printed matter color difference detection device is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS
