​Printing proof - a primary step for quality packaging printing

There is always a color difference on computers and product packaging. Because the color on the computer is the RGB color system, while the printing color system is CMYK.
 
Proof printing is the solution for this problem.

What is proof packaging printing?

Put simply, a proof is a sample done before a series of offset printing. Sometimes, the designer will make mistakes about color, spelling, calibration so proof is considered the best solution to check all errors before printing the finished product.
 
When you bring the desing file to the printer, you also need to bring the proof copy, so that based on that, the printer will compare and produce exactly the product packaging you want. These factors are:

• Information content, images: Is there a typo? Is the image reasonable? Is there any unreasonable content?
• Fonts: Choose the right font? Size, color or errors related to handwriting alignment.
• Color: What is the color deviation? Is this color good? Need to change color parameters or not?
• Graphic symbols
• Adjust margins, layout of bricks, writing

What is the benefits of proof packaging printing?

• Save time and money

Based on proof prints, designers know exactly color deviations and other technical errors to quickly correct the necessary errors, customers know the final finished product soon. For approval, the printing facility has facilities for mass printing.

This helps to shorten the time of pre-batch printing. Besides, offset printing undergoes a lot of stages, long preparation time, often easy to deviate colors. Therefore, proof printing is an important preparation stage, minimizing risks before mass printing.

• Ensuring accuracy

Compared to fast printing, proof printing is rated superior. Because the color resolution mode of proof printing is similar to offset printing, it is the basis for printing color, usually from 90% - 100% depending on the product. Because proof printing is the color standard for offset printing, not inkjet or laser printing technology.

• Customer satisfaction

Proof print is not only a form for offset printing, it is also proof of agreement on printed products and printing workshop when there are any problems of finished products. Because the sample printouts requires customers to sign the color of the printouts, the manufacturer can begin mass printing.
