1. Estimated length of time and working process
A total of two printing operations are required, namely calibration basic printing and characteristic printing, each taking about one to two hours, and half an hour to an hour of plate correction in the middle, about half a working day. All work should be arranged on the same day, and completed by the same operator on the same equipment materials.
2. Equipment
The printing machine should be adjusted to the best working state, including consumables, and check whether the related physical and chemical parameters meet the requirements. According to the requirements of the manufacturer, adjust the focal length, exposure and chemical syrup of CTP, and use the natural curve without linearization correction to publish. Select the dedicated empty channel for G7 in RIP. The number of halftone dots is 150 or 175. For symmetrical dots, such as square dots, the angles of the meshes that can be used are usually C15 °, M75 °, Y0 °, and K45 °; for asymmetric dots, such as chain For outlets, the K version uses 135 °. K and M are interchangeable.
Use ISO1 # paper with as little fluorescence as possible. See the table below for the chromaticity parameters of the paper. Approximately 6,000 to 10,000 sheets of paper are required, depending on the operating efficiency.
3. Paper
Use ISO1 # paper with as little fluorescence as possible. See the table below for the chromaticity parameters of the paper. Approximately 6,000 to 10,000 sheets of paper are required, depending on the operating efficiency.
4. The ink uses ISO2846-1 ink. The parameters of basic color ink and overprint color are shown in the table below. The data is measured on white backing paper.
5. Standard proofs
You can purchase the preset "GRACoL7 Printing Press Calibration Sample" from the website, or you can do it yourself, see Figure 4. Standard proofs should include:
· Two copies of P2P23 × standard (or newer version), and 180 ° to each other
· GrayFinder20 standard (Figure 10) (or newer version)
· Two IT8.7 / 4 characteristic standard samples (or equivalent), 180 ° to each other, and arranged in a row.
· A half-inch (1cm) (50C, 40M, 40Y) signal strip with full paper length across the cloth.
· A half-inch (1cm) 50K signal bar with full paper length across.
· A suitable printer control bar should include some important parameters of G7, such as HR, SC, HC, etc.
· Some typical CMYK images.

6. Others
Other equipment includes:
· NPDC drawings provided free by GRACoL ()
· The printing plate dot measuring meter measuring the printing plate · Spectrophotometer · D50 Observation light source · Curve ruler for drawing (Figure 5)
Note: GRACoL software IDEAlink can also be purchased to help complete the test quickly.

Customers would normally custom O Bag Handles as Rope Handles, and PU handles, which can be 44cm short to 86cm long handles. Some kinds of bags are sling shoulder bags it would need long PU straps. All handles and straps can be custom pattern printed or solid color. The MOQ would be 300units per color, 1500units MOQ for per order.
