In the packaging and printing market where opportunities and challenges coexist, the competition among printing companies is becoming increasingly fierce. To survive and develop, an enterprise must have orders that meet the company's ability to survive. This poses higher requirements for packaging and printing companies in the new era.
The establishment of a full-process color workflow is a very effective way for packaging and printing companies to improve their competitiveness. From the most basic standards, specifications, and training to the most complex global process design, packaging companies should step by step to establish a standardized process that meets their needs. We hereby recommend some suitable standards, specifications, processes, equipment, and training for you. In this way, color accuracy and consistency are achieved, thereby realizing the high quality of the product. Use continuous assessment, support, and performance tuning to streamline your processes, transform your color management processes into real benefits, and gain competitive advantage.

To realize a complete packaging supply chain, it is necessary to establish the steps of color standardization for packaging companies, and to determine what specific products are needed in each link to achieve process control.
First of all, the steps of color standardization may include three major aspects as follows:
1. Establish standards;
The establishment of standards refers to the use of quantitative methods to clarify the evaluation criteria of product quality. The specific figures are used to measure the quality of the products. The specific data evaluation needs to be implemented by the measurement and control bar tools. The contents of the measurement and control bar must include four-color field blocks. Chromaticity values, density standards and tolerances, standards for four-color dot gain values, gray balance standards and tolerances, spot color differences (color differences between printed products and customer signatures), and spot color uniformity, etc. The parameters of control for each enterprise can be adjusted according to their actual situation.
2. Establish processes and achieve standards;
After clarifying the standards, it is necessary to clarify what links the printing process needs to include in order to understand the process of color transfer in the factory.
The complete package supply chain process for packaging companies, including image capture, graphic design, plate making, color mixing, digital proofing, customer signing, printing and other links. What should be done in color management for each link, as follows:
Image Acquisition: The purpose of this session is to use a digital camera or scanner to capture the items the customer needs in digital form. The accuracy of the collected data is crucial for the later image restoration and ensures the best state of the image acquisition equipment. Consistently important steps in capturing a perfect work must include linearizing the image device, such as creating an independent ICC profile for the acquisition device, a DNG profile, custom white balance, and accurate restoration of gray balance.
Want to achieve linearization or custom color and other processes, you can use X-Rite ColorChekerSG, Classic, Passport and other series of color cards to complete.

Graphic design: This work is done by the designer. The acquired image needs to be designed according to the customer's requirements. During the design process, the designer observes most of the image is done on the display and the proof, and the monitor is Linear calibration and regular QC inspection are very important, so that the true color of the picture can always be reproduced. In addition, when the designer revises the manuscript, he needs to select the creative color and print the picture according to the customer's requirements, thus facilitating the accurate color collection tool. Standard light boxes that accurately reproduce colors are also necessary for designers.
To achieve the above requirements, you can use ColormunkiDesign, i1PhotoPro2 Kit, JudgeII standard light source light box.
Plate making: The quality of the plate has a great influence on the printing quality. Checking and controlling the reproducibility of the printing plate dot area is a very good method for managing the plate making process. The reduction of the dot area affects the value of the final printing media, and the reduction of the dot quality affects the printing product. Image quality is good and bad. In addition, due to the instability of the publishing process, the dot recovery will change at different times. Therefore, it is very important to select an appropriate plate measuring instrument for daily plate-making quality inspection and control.
You can choose iCPlate2 to do this work.
Ink mixing color: For packaging companies, with the increase of creative products, customers need more and more spot colors, spot colors are common in the printing process, the traditional color matching process is dependent on the experience of color master, so It will cause problems such as low color matching efficiency, waste of spot color ink, and waste of on-machine printing costs. Computer color matching can greatly improve the color matching efficiency and accuracy, and the weight of spot color ink can be accurately formulated according to the needs of each single job. In this way, it is possible to prevent the waste of costs due to multi-inking, and the computer color matching system uses a spectrophotometer to accurately match the sample and the printed product, and the spectral curve and the color difference are used to judge the accuracy of color matching, and no light source environment is generated. Effects on color observation.
A color matching system needs to include items such as color matching software, spectrophotometer, color development instrument, electronic balance, and standard light source box. The color matching software can select InkFormulation6. The spectrophotometer can use SpectroEye or X-Rite939.
Digital proofing: compared to commercial printing companies, packaging companies have more ways to achieve proofing. This is also related to the particularity of packaging materials, but the basic proofing methods include traditional proofer proofing and printing.
Proofing, digital printing press proofing, ink jet printer proofing, etc. The use of traditional proofing methods, printer proofing and printing link control are similar. Regarding the control method, it will be explained in the printing process. For the digital printing machine proofing, it needs to be digital. The linearization process of the printing machine also requires the printing of the characteristic document as the goal. The digital printing machine is subjected to closed-loop calculation to match the proofing and the printing color. The inkjet printer is similar in method to the digital printing machine. The process of linearization and closed-loop correction is needed.
To achieve the color management requirements for digital proofing, the i1PublishPro2 suite can be used.
Customers signing samples: With the standardization of management methods, more and more customers choose to use measuring instruments to evaluate the matching degree between samples and printed products, and the use of color difference methods can more quickly and accurately check the printed products; If the customer still uses the human eye to judge the degree of matching, it is necessary to recommend a standard light source environment for him to reduce the interference caused by homochromatic spectrum on color matching.
SpectroEye/500Series colorimetric instruments, JudgeII standard light source light boxes, and professional quality inspection and scoring software can be recommended.
Printing: This link is the most important for the quality reproduction of the final printed product, and the control is also the most complicated, because the printing press itself is much poorer in stability than the display, proofer, and publishing machine used before printing, and the printing The machine itself also has more variable factors in operation, such as fountain solution stability, ink quality, printing pressure, paper, temperature and humidity in the printing shop, paper feeding, and many other aspects of control. The prerequisite for the standardization of printing color management must be the unity and stability of various types of raw and auxiliary materials. Only in this way can the printing machine be conditionally controlled in a stable manner, and then the printing machine can be linearized and the standard data can be printed. Property file.
The premise of obtaining standard data is that all aspects of the control of printing parameters need to meet the standard requirements, such as density, chroma, dot gain, and gray balance.
Accurate measuring instruments are necessary when using density, chromaticity, and other parameters for printing control. You can select handheld or automated measuring instruments. You can choose SpetroEye or X-Rite 500Series for handheld instruments and IntelliTrax for automated measuring instruments. And EasyTrax can choose, automated measuring instruments in 5
The measurement efficiency is much higher than that of the handheld, which can help companies adjust the color and control the stability in real-time during the pre-printing stage or the actual production process. The instrument coordination software can quickly help the printer get the best color matching.
Profiles can be created using ProfileMaker Packaging to generate any spot color profile.
For printing substrates with higher gloss, such as gold and silver cards, pearlescent products, X-Rite SP series integrating ball instruments can be used for measurement, and the method of eliminating specular light can achieve accurate color collection of glossy substrates.
3. Management processes, maintenance standards;
After the complete establishment of a good color flow, the next important task is to maintain these standards. That is, we need to do a good job of QC inspections in all aspects, use tolerance data, and manage product quality. X-Rite has designed a very good QC inspection software whether it is in front of the screen soft proofing, digital proofing, or in the back end of the printing link, can help customers achieve a very fast quality stability check, but also can be a manager Using very good management tools, measurement data can be directly printed out as a basis for quality inspection.
The above is the author's use of the world's leading X-Rite color management products and solutions for some of the packaging company's understanding of color management applications and understanding, for your reference only.
