In view of the printing machine manufacturers continue to promote the 7-color flexo ink system processors, Mr. Nilpeter America's Chris Baldwin in this article we will analyze a wide color gamut printing requirements, challenges and advantages.
What is extended gamut printing? Generally refers to 7-color printing, namely yellow, yellow, black, black and orange, green and purple. Extended color gamut printing is also known as wide color gamut printing, high fidelity printing, and fixed ink set printing. In general, "wide color gamut printing" refers to the quality aspect of the printing process, while "fixed ink group printing" refers to the economic aspect, which we call "wide gamut printing" or "EG printing".
This article is aimed at companies that are ready to get involved in wide color gamut printing, and will answer common questions that may be encountered, including: Why do you want to print in wide color gamut? What preparation is required for wide color gamut printing? How to print in wide color gamut?
Why do you want to print in wide color gamut?
There are a number of reasons for wide color gamut printing, but they fall into two broad categories: economy and quality. How can companies get higher profits? How to achieve higher quality printing of labels /packaging? The first thing that modern companies consider is profitability, so let's start with the economics. Most companies have realized that the current label is not the high-margin industry.
As the cost of materials such as substrates, inks and plates continues to rise, and customers are constantly demanding lower prices and shorter lead times, profitability is becoming more difficult or even difficult for printers. For succession. Due to external factors such as the cost of substrate materials and the price of crude oil, printers must control internal factors. This is the focus of our attention, how to achieve more efficient and profitable printing through wide color gamut printing, because efficiency and cost are closely related. Let us first look at the impact of wide color gamut printing.
Save on ink - Many printers store a lot of ink in the warehouse, some use half of the ink, and there are only a small amount of special color ink for individual orders. Often hundreds of liters of ink are stored in the warehouse, but it does not bring any profit to the company. With wide color gamut printing, only seven colors of ink are required.
Fewer anilox rolls – with wide color gamut printing and only seven printing units, the number of anilox rolls can be reduced. Only a few anilox rolls need to be prepared for coating, white ink and line color, so the stock of anilox rolls can be greatly reduced.
Reduced cleaning - Since the same seven-color printing is basically used, there is no need to clean the equipment when the job is replaced. This not only saves the preparation time for the next order, but also allows more printing time to increase productivity. In general, the operator only needs to change the plate.
Co-printing - In most cases, co-printing requires the same spot color for different jobs. The use of wide color gamut printing will not be restricted, operators can simultaneously print jobs of different colors and different specifications. At the same time, the combination printing will greatly increase the output of each working day.
Material savings – Wide color gamut printing allows standardization of the printing process, eliminating the need to use the press as an expensive ink proofer. Matching colors on the machine is the most waste of time and material. Just from the point of saving materials, there are enough reasons for companies to seriously consider wide color gamut printing.
As with the five aspects listed above, companies can increase efficiency by controlling internal factors – and more importantly, increase profitability.
Higher quality
Now focus on how to use high color gamut printing to produce high quality labels.
With wide color gamut printing, the range of colors that can be printed is wider because seven-color inks enable a wider color gamut. Flexo printing with four-color inks can only match approximately 50% of Pantone, while wide color gamut printing can match 75% or more of Pantone.
The problem often encountered by processing companies is: Is it worthwhile to add three colors only to increase the Pantone color by 25%?
This is a very important issue. In short, it seems worthwhile in my opinion. In the G7-ISO color standard, Delta-E must be less than 5 for color matching. Obviously, some big brands of FMCG companies have stricter color requirements, and only a few companies are not as strict as they are when implementing standards.
Although adding three colors can only reproduce 25% of Pantone color compared to standard four-color printing, using seven-color printing for colors outside the color gamut will be more accurate than four-color printing. For example, there are 1000 spot colors in the color table, only 500 of them can be matched by four-color printing, and 750 can be matched by wide color gamut printing. More than two colors of ink can reproduce 250 colors.
Using wide color gamut printing, the graphics containing orange, green, purple and other colors are more vivid than the standard four-color printing. The extra added ink will make the label and packaging photo-realistic and must be more compelling.
