How to use measuring tools in flow control of Small Cigarette Hinged Lid Box G7

 

Using the G7TM proof-to-print (from proofing to printing) process will not only help you reach international production standards such as ISO
It can also improve your overall process, reduce waste and downtime, and increase productivity, thereby helping you save money and stay ahead of the competition in the marketplace.

 

Process control is the way to stay ahead of the market

The use of prepress operations and print shop measuring tools -- plate gauges, spectrodensitometers, and automatic scanning systems -- is critical to the smooth implementation of the G7 proof-to-print process. This article provides an overview of the use of various measuring devices in prepress color management and print shop workflows, and explains how the information and data provided by these devices can help you reap the many benefits of G7 process control.

 

Throughout the history of modern business, people have been building processes for almost everything that needs to be done, from making decorations to paying vendors to managing employee salaries.

 

In today's tough economy, business owners are always looking for shortcuts to strengthen their balance sheets, but the truth is good process control is a better way to reduce wasteful expenses and increase ROI. When everyone is trying to stay ahead of the competition, plan their next move, and retain customers, implementing a stable process is a strategy to ensure the long-term survival and development of the enterprise.

 

This is especially true in an industry where competition is fierce, margins are thin and customer satisfaction (and retention) is tied to the quality of each item printed. At the same time, for many printing enterprises, color accuracy is often synonymous with printing quality.

 

G7 process control case

The printing world has long been looking for a way to ensure that the colors used by designers and the colors printed by the printing press better match visually.

 

There are a number of reasons to do this: Once you have the ability to predict the print effect and better predict the print you will get from the press before you go to the machine, you will have fewer reprints, shorter printing cycles, less waste and less stand-by time, giving you immediate cost savings while delivering superior color prints. In addition, you can demonstrate print quality through realistic printing guidelines and targets, which enhances communication between printers and print buyers.

 

Recognizing this important industry need, the IDEAlliance GRACoL (General Needs and Applications of Business Lithography) Committee set out to develop a simple calibration process to help printers achieve higher compliance "visual matching" from proofing to printing. [next]

 

The G7 proof-to-print process, as the name implies, is a new method of color calibration for printing and/or proofing. G7 is to establish a circular system of appearance, that is, from the printing buyer to the design house to the printer and back to the printing buyer.

 

IntelliTrax displays G7 results for easy data analysis. Display content: HR, HC, SC and neutral print density of corresponding black screen/mesh.

G7 has created many surprises in the printing industry because with this approach you can print on any type of press and any substrate and still maintain a continuous and consistent visual appearance.

 

G7 is not only suitable for business printing, but also for publishing and news printing, flexographic printing, screen printing and inkjet printing.


The G7 proof-to-print process is based on the principles of digital imaging, spectrophotometric densitometry and direct plate-making technology. G7 is based on the theory that the visual appearance (the image seen by the eye) from shadows to highlights can be best controlled by shades of grey rather than by measuring dots on the paper. The G7 name comes from the gray correction (G) technique and the seven (7) ISO inks, which focus on gray balance chroma data for each color's highlights and midtones, rather than on density measurements for each color (such as field density and dot expansion).


The G7 defines grey balance and "neutral print density curve" (NPDC) and uses these as the basis for calibration and image reproduction to ensure that documents created using the G7 method have a similar visual appearance regardless of the printing process used.

 

The importance of measurement tools in the G7 approach

The use of automated color management tools is critical to the implementation of the G7 proof-to-print process.

 

Not only do they maintain and monitor the calibration process, but they also simplify the overall workflow by ensuring accurate and traceable data is obtained every time. -- DavidSteinhardt, President and CEO of IDEAlliance®

 

GRACoL's research shows that dot measurement is not the only way to achieve a consistent visual appearance across devices. The G7 print calibration method uses spectrodensitometry to track neutral grays to improve tone and gray matching. Therefore, the spectrophotometer is a key element of the G7 process.

 

Measuring tools are critical to obtaining and maintaining G7 conditions in three major processes of the G7 process: the use of i1 measuring equipment to verify proofs in the proofing process; Check plate quality at the printing shop using iCPlate2 or PlateScope; Complete the process using a handheld spectrophotometer (such as the 530) or the IntelliTrax automated scanning solution. Using these tools in the G7 process ensures consistency in process control.

 

One of the important goals of the G7 process is to implement a consistent flow control solution to enable users to understand the specific process between proofing and printing. There are many aspects of this process that can be considered from a measurement perspective.

 

The G7 process begins with a proof test by measuring a P2P color scale in a linear format, usually using an Emily i1 spectrophotometer. Information output from the measuring tool can be easily imported into IDEALink Curve software and evaluated according to the G7 process. [next]

 

The G7 process is commonly used in direct platemaking (CPT) processes. In order to ensure the reliability of the plate, it is necessary to calibrate the plate process. A ladder is placed on the plate and then measured using a video-based plate measuring tool such as iCPlate2 or PlateScope plate control technology.

 

Once the proofs have been verified and the plate curve generated, the next step in the process is to ensure that the actual press used can be calibrated and configured in the G7 process.

 

The process in the printing shop is the same as that in the proofing process. Users can use an automated scanning system such as IntelliTrax to scan and output the G7 P2P target color table in seconds. This data can then be imported into IDEALink Curve software so that the results can be compared with an ideal NPDC curve. The Curve software will suggest any corrective actions required for RIP. Automatic action allows the user to repeat the validation process until the desired result is achieved.

 

Once process calibration has been completed within the G7 process, it is important to ensure that daily operations support this process. Typically, you can do this by using measuring tools and periodically monitoring plate values and ash balances on proofs and sheets. In this way, users can ensure that each print is consistent and complies with the G7 guidelines for successful colour management.

 

The specific capabilities of the IntelliTrax automated scanning solution make daily evaluation and inspection of prints printed in the G7 process easier. It can be monitored by timing sampling measurement and control strip. This approach is specifically set up to support G7 workflows.

 

Printing professionals can track business trends and use the data in their daily maintenance processes, which is another benefit of using fully automated systems in G7 processes.

 

Users can easily view the brightening range (50/40/40), brightening contrast ratio (25/19/19) and darkening contrast ratio (75/66/66) as specified in the G 7 process, and check the field density of CMYK against the set color scale. According to the visual presentation of the G7 gray color label, it is easy to determine the difference between printing and gray balance and what adjustments should be made to the field ink in order to achieve gray balance. In addition to using an automatic scanning solution, manual measurements can also be made with a portable instrument such as an Essalie 528 or 530. After loading the G7 reference values, the device will display dE and/or other parameters against the G7 field tone and grey balance color scale. This method can also save users time and money by making gray balance easier and faster.

 

Benefits of fully automated G7 processes

G7 sets a simple calibration process to help printers achieve a consistent high visual match from proofing to printing, providing tangible benefits to creative parties, print buyers and printers.

 

Reports from printing companies indicate that when fully automatic plate control technology is used to produce plates, the matching of proofs and final prints takes less time and the plates are reproduced less often. For printers, using this process can help reduce printing preparation time and improve customer satisfaction. With G7, printers can separate prints on different printing equipment or even print in different locations.

 

Using systems such as IntelliTrax or portable density spectrometers means printers can produce visually similar prints using different devices, even in different locations. According to the report, separate sheets on an old and a new device look so similar that no one can tell which sheet came from which press.

 

The use of fully automatic measuring tools to implement flow control can greatly reduce the cost of materials and labor in the production process.

 

The key to success is not only one-off process creation, but also taking advantage of the available measurement techniques to automate the process and ensure that every piece of print is printed in accordance with the G7 process on a daily basis. Using fully automated solutions can help you achieve these goals. Using these tools, your printing will be more accurate; You can quickly know whether the printing of the printed goods in line with the process; If not, these tools can help you gather the necessary data to make corrections. This saves you a lot of time and money.

 

Become a serious competitor

Implementing the G7 process using measurement tools will enhance communication between printers and customers, helping to avoid unrealistic expectations and disappointments. Having fully automated, repeatable G7 processes increases productivity, maximizes technology investment, and helps printers stay ahead of their competition. G7 processes deliver superior solutions that meet customer expectations and drive print to become a strong competitor in the communications market.
