How to distinguish between printed and printed images

How to distinguish between printed and printed pictures:

Traditional printing uses oil-based inks, while printing uses water-based inks.

Traditional printing color printing process is a four-color overprint, while printing is a 6-color or 8-color overprint, which explains why the same document, the color of the printing and printing of the color there is a big difference between the reasons.

The ink viscosity of traditional printing is greater than that of printing, so printing has better ink adhesion than printing.

Printing can be in accordance with the different substrates in a variety of printing methods to choose a suitable, these printing methods are offset printing, letterpress printing, gravure printing, screen printing, transfer printing, etc., according to the different printing methods, respectively, can be in rubber, metal, paper, plastic, glass and other kinds of substrates to print out the desired content, and printing can only be in the ordinary paper work.

Summarized as follows:

Printing is through the distribution of dots to present the image, while the color printing of the picture is according to the printer's ink spot distribution to show the fineness of the printed photographs, the accuracy of the printing is far lower than the printing.

The printing method requires a plate to be made and then printed, while the printing method eliminates this aspect.

Printing format can reach 1194mm * 889mm, while the current maximum print format of 330mm * 540mm, printing in this piece has a great advantage.
