The color management software generally includes a printer's ICC file and a printed ICC file. The ICC file benchmarks for printers used by different color management software are different, so printer ICC files cannot be common across software. Such as COLOR PROOF and SCREEN PROOF two software, before doing the ICC Profile first need to adjust the printer's basic linearity, control the printer's ink output, and then the data measured by the spectrophotometer and the printer's basic linear combination to generate a printer ICC file (Paper Profile); and the Color Tune software's printer ICC file is generated in conjunction with the printer density curve. The establishment of the printer ICC file has a close relationship with the printing ink droplet combination method, ink output, resolution and other printing parameters. Different ink output and resolution need to use different printer ICC files.
In theory, the printer's ICC Profile should be fixed with a fixed printing device, media, and ink type. However, due to differences between the same type of printing equipment, media and ink, such as: the same type of inkjet printer, the working status of different printer print heads is not the same, the amount of ink jet is not the same, so that the output The imaging characteristics are also different. Therefore, this requires the digital proofing color management software to achieve a certain standard by correcting the amount of ink discharged (printing density) of the printer so as to realize the versatility of the ICC Profile of the printer itself. When the working conditions of the digital proofing system change, only the amount of ink (print density) corrected for the printer can be used to ensure the color stability of the entire proofing system. However, due to environmental, equipment, consumables and other comprehensive factors, simply using software linear (density) correction can not make different systems meet the same standard, so the actual digital proofing to achieve better results, you need to each proofing The system makes a personalized ICC profile to introduce differences between different systems. However, most of the personalized ICC profiles will increase the debugging difficulty and cost of proofing, hinder the realization of the standards of the proofing system, and weaken the controllability of the digital proofing system. Therefore, it is necessary to solve the benchmarks of the proofing software itself and the system equipment consumables. The standardization of the environment and measuring instruments will eventually realize the unity of the ICC Profile.
The printed ICC file is obtained by measuring the color table printed by a spectrophotometer (different spectrophotometers use different color tables). All color management software can use the same printed ICC file. However, different printing companies use different PS plates, different papers, different inks, different printing machines, different printing conditions, etc., resulting in certain differences in the printed ICC file information. Therefore, in China, printed ICC files will follow It varies with the printing factory.
After establishing the conversion relationship between the ICC Profile and the printed ICC Profile through the digital proofing color management software, from the perspective of the design philosophy of the color management software, the matching between the proofing results and the printing results is realized, that is, the proofing color and the printed color are achieved. Consistent. However, in the actual production process, all color consistency requirements cannot be fully satisfied. The reasons are as follows:
1. The color blocks for ICC Profile testing can only have limited color space. The transition color between them can only be simulated by software operation. At the same time, the color management software can only control the color of the device through a limited number of points. Therefore, it cannot be guaranteed absolutely that there is no color difference.
2. The spectral characteristics of the proof ink are inconsistent with the spectral characteristics of the printing ink, while the spectrophotometer only reads the chromaticity value under the standard light source, and this value cannot be guaranteed to be consistent under any light source.
3. There is a certain difference in the stability and uniformity of the printing proofs provided for reference, and the sample will have some color drift.
4. The stability of the proofing system itself, the error of the measuring instrument and the environment will affect the consistency of the color.
5. The same sample showed different colors under different lighting conditions, viewing angles, background colors, etc.
6. The viewer's subjective feelings can cause inconsistencies in the sense of color.
Now, color management software and specialized ICC production software packages can basically solve the above problems through different approaches (such as curve adjustment, individual color adjustment), reduce color errors, and meet the different needs of actual production.
A training chair is a seat designed specifically for activities such as training and meetings. It has the characteristics of comfort, durability, and ease of movement, which can meet the needs of different groups of people. Training chairs can be classified into various categories based on material, structure, function, and other aspects. Below will be a brief introduction to the classification of training chairs.
1. Material classification
The materials of the training chair mainly include metal, plastic, and fabric. Metal training chairs typically have strong stability and durability, making them suitable for long-term meetings or training activities. The training chair made of plastic material has the characteristics of lightweight and easy to clean, making it easy to arrange the meeting site at any time and suitable for use in multifunctional halls and other places. The training chair made of fabric has a comfortable sitting experience and good breathability, making it suitable for long-term meetings or training activities.
2. Structural classification
The structure of training chairs mainly includes single chairs, linked chairs, and foldable chairs. Single chairs are the most common training chairs, with each seat being independent and adjustable as needed. Chainage refers to the connection of multiple seats together, usually in the form of one or more rows, suitable for use in large training venues. Stackable chairs are training chairs that can be folded and stacked, saving space and facilitating storage and handling.
3. Functional classification
The main functions of the training chair are adjustable, rotatable, foldable, and storable. The adjustable training chair can adjust the height and angle according to personal needs, providing a more comfortable sitting posture. The rotatable training chair can rotate 360 degrees, facilitating communication and interaction with people around it. The foldable training chair can be conveniently stored and transported, making it suitable for use in multifunctional halls and other places. The training chair that can store items is designed with storage space below or behind the chair, making it convenient to store items such as stationery and documents.
In summary, the classification of training chairs mainly includes material classification, structural classification, functional classification, etc. Choosing a suitable training chair can provide a better user experience and improve the effectiveness of training and meetings.
