  In the process of commercial transactions, proper quality evaluation of color box printing is particularly important. The complexity of the color printing process is well known, and the production of a gift packaging box involves over a dozen processes, with printing being the most crucial link. It serves as the starting point for determining the overall quality of the color box. Therefore, strict color box printing procedures need to be established. Controlling color deviation in color box printing is the core of the entire printing process.


Let's first discuss the classification of color deviation, which can be divided into:

(1) Original Manuscript Color Deviation: Reproducing the color tones of the original manuscript is the goal of printing replication, aiming for a level where it is challenging to distinguish between the printed product and the original manuscript.


(2) Batch Color Deviation: Refers to the color deviation between different sheets in the same batch of products in the same hue area at the same position.


(3) Batch-to-Batch Color Deviation: Refers to the color deviation between different batches of the same product. If each batch of printing shows slight differences in color, customers may perceive these products as having different ages, even raising concerns about the consistency of their intrinsic quality, leading to mistrust in the product quality and dissatisfaction with the printing factory's product quality. Dongguan Beilin Packaging Box has printing equipment and experienced printing workers, ensuring product quality within standard ranges.

  

  Both customers and printers hope that the numerical value of color deviation is zero. However, due to various conditions in actual production, completely eliminating color deviation is almost impossible. It can only be achieved by strengthening quality control at all stages, ensuring that the color quality differences of the product are within the specified color deviation standards. Color tolerance refers to the acceptable color deviation between the printed product and the original manuscript or proof.

  How to judge color deviation? Firstly, there is the subjective evaluation method. When subjectively evaluating the color quality of printed products, a visual method is adopted. Observers visually inspect the printed product and compare it with the original manuscript or proof, making their judgments based on how well the color quality of the printed product matches the original. Dongsheng Printing has established strict printing quality control procedures, faithfully reproducing color deviations.

  

  Whether during the color box printing process or quality inspection after printing, operators or quality inspectors should rely on their feelings and experience to evaluate the color quality of printed products based on fidelity and realism. Fidelity refers to the degree to which the color tones of the original manuscript are reproduced in the printed product. As a reproduction, the color reproduction process of the printed product is based on the original manuscript from pre-press processing to printing. The goal is to faithfully reproduce the color tones of the original manuscript. The degree to which the printed product matches the original manuscript is the subjective evaluation standard.

  

  When there is no original manuscript for comparison, the color quality of the printed product is related to realism, requiring it to match the memory color of most people. Generally, people have preconceived habits about common objects, and if the main color in the printed product differs from the real object's color, the printed product cannot be considered a high-quality reproduction. In summary, the subjective evaluation criteria for the color quality of printed products are to reproduce truth, nature, and harmony. Of course, sometimes it may be slightly altered according to the customer's intention or the product's use.

  

  The objective evaluation of the color quality of printed products is calculated through statistical means to obtain the results of subjective evaluation and then convert them into corresponding physical quantities for use as objective evaluation standards. This can eliminate the influence of human factors on evaluation, allowing for a fair assessment of the color quality of various printed products according to standardized unified criteria, ultimately making it more in line with the subjective evaluation standards of the majority of people. Objective evaluation methods mainly use specific measuring instruments and tools to measure some standard elements printed along with the printed product image. Only through measurement can automatic quality control of printed product color become possible to some extent. With 24 years of experience in cosmetics and production, Dongguan Beilin Packaging Box Co., Ltd. is a source factory.
