Best Color Color Management Software
Best Color color management software has been in the country for many years and is familiar to the industry. The company that developed this software, Germany Best GmbH, was founded in 1994. It now has branches in the US and Malaysia, and has branches in Shanghai, France and Latin America, China, which has a global sales network. From January 2003, Best became a division of EFI (Electronics For Imaging).
Software version classification
There are three main versions of Best Color color management software: Design Edition is mainly for low-end users; Color Proof is for intermediate files before RIP and some RIP; Screen Proof mainly deals with 1-BIT TIFF files generated after RIP, which covers All the features of Color Proof.
Software kernel
Best Color color management software uses the EFI kernel for color management. RIP processing uses the core of the world-renowned RIP vendor ADOBE - ADOBE PS3, so the software supports optional calculation accuracy, workflow and double-byte fonts.
File types that can be processed
Both Color Proof and Screen Proof software have been upgraded several times and are now version 5.0. There are many file types that can be processed. Color Proof 5.0 mainly handles TIFF, JPEG, EPS, PS, PDF, DCS, Delta List (intermediate files generated by Heidelberg Delta RIP), CT/LW, TIFF/IT, etc. In addition to these file formats, Screen Proof 5.0 It can process the screening files that have been processed by RIP - files in 1-BIT TIFF format and HQ/PGB (intermediate files generated by HQ RIP), Founder/FMP (intermediate files generated by Founder RIP), and so on.
Software supported fonts
Color Proof and Screen Proof software can support the installation of PS fonts, and now the upgraded version 5.0 supports the installation of CID fonts in the test.
Software and hardware environment required by the software
Color Proof software recommends using a P4 1.0GHz or higher computer with more than 256MB of memory, while Screen Proof software recommends a dual-processor computer with P42.0GHz or higher and more than 512MB of memory. Both software require a computer with a free USB port and CD or DVD. driver. System software requirements are Windows 2000 Server, Windows XP Server system. The Design Edition software runs on the MAC and the required operating system is OS X.
Software interface
Best has its own translation company in Germany, specializing in the translation of software interfaces into various languages. Therefore, Best Color color management software is Chineseized, and the operation interface is Chinese interface, which is convenient for domestic users.
Software parameter adjustment
Best Color color management software has been continuously improved and updated, and it has its own characteristics in color adjustment. Color Proof and Screen Proof software adjusts the printing device by adjusting the total ink volume, adjusting the single-channel ink volume, forming the printer's basic linearity, paper white adjustment, and basic linearity verification. Previous versions of Color Proof and Screen Proof software were cumbersome to do these tasks, and some of the values needed to be done by the adjuster's experience and understanding of the colors, which inevitably resulted in different colors due to different human perceptions. deviation. The current version 5.0 turns these tasks into software and calculates them by measurement, which reduces the deviation caused by human factors. When the operator makes adjustments, he only needs to follow the software prompts to perform the "next step" operation and perform "printing- Work - measurement - reprint - remeasure...".
On this basis, Best Color also introduced another optional plug-in software package - Best Premium, which is a combination of hardware and software, including Colormanager, Remoteproof and Best Eye. Best Eye is a portable spectrophotometer that combines with Colormanager to generate ICC Profile files, and it can also be used in conjunction with Remoteproof as a quality control tool. Color Proof and Screen Proof software, combined with the Best Premium software package, greatly enhances their capabilities by creating printer linear and printer profiles (ICC Profile files) in color management software, as well as generating print profiles without the need for third parties. The combination of software avoids subtle deviations in data caused by software differences. In addition, the Best Premium software package can be automatically closed-loop corrected, which means “unlimited access”.
Printer linear measurement
Generate profile
Printer linear fine adjustment
Another feature worth mentioning in the Best Premium software package is that when making two adjustments, the printer line and the plate compensation curve, the corresponding 0 and 100 points are adjustable, which is not available in previous versions. It makes fine adjustments more accurate. However, the Best Premium software package can only be used in conjunction with Color Proof and Screen Proof software, and requires more accurate print proofs, including solid density, dot enlargement, and uniform ink color during printing.
As a low-end product, the Design Edition software is not as powerful as the above two softwares. It fixes some profile files (ICC Profile files) in the software for users to select and cannot generate or call the user's own profile. At the same time, it is not possible to use the profile generated in Color Proof and Screen Proof software.
Software adjustment of spot colors
Best Color has been certified by PANTONE to embed color values for PANTONE spot colors in Color Proof and Screen Proof software. At the same time, it can be judged in the software whether the spot color exists, and the name of the spot color corresponds to the PANTONE color, and the corresponding color value is found and printed. But there is no good solution for gold and silver.
Software remote proofing function
In the Best Screen Proof software, you can select the "Export" item to generate a file of the files to be printed and the corresponding printer linearity, profile, print profile, color patches and patches used for measurement, and locally measured Lab values. Transfer this file to an offsite print. Of course, this alone is not enough. A photometer, Best Eye, is needed both locally and remotely to measure the Lab value of the color patch and calculate the color difference ΔE value. For users who have purchased the Best Premium software package, remote proofing is more convenient and reliable. An adjustment tool to ensure the color consistency of two or more printers has been added to the Best Premium software package to ensure color consistency when remote proofing or multiple printers work together. Design Edition software does not currently support remote proofing.
Review
According to the above introduction, the characteristics of Best Color color management software are: software color adjustment function is powerful, most of the work is calculated by software based on measurement results, reducing the color difference caused by different personnel experience and understanding of color, and It has certain advantages in remote proofing. Best Premium software package is more convenient to use with software, and the print quality is better, but the requirements for printing proofs will be higher. Therefore, users are required to have good printing equipment, materials, environment and other factors when printing proofing proofs. control. For the Design Edition software, there are few adjustable links. It is a low-end product and the price is relatively low. We call it a "powerful MAC print driver" for the time being.
