Master Exquisite Picture Book picture processing ideas, methods and skills

Picture processing is a complex work combining technology and artistry. Not only the technical aspects require operators to be familiar with the whole printing process and understand the relevant parameters of printing suitability, but also the artistic aspects require operators to have a high artistic quality and aesthetic perception. Only in this way can we accurately analyze and flexibly deal with all kinds of pictures, turning the rotten into the magic! If there are errors in the basic color separation parameters of image processing software, the ideas and methods of image processing personnel are not scientific, and the skills of dealing with various picture types are not flexible, even if the later stage of plate making and printing have reached the required standards and specifications, the quality of newspaper pictures will be greatly reduced, so the picture processing link can be regarded as the top priority in newspaper printing. Its ideas, methods and skills need special emphasis. As follows:

(1) Principles of image processing
Both authenticity and artistry
"Color mixing" and "drawing" in parallel
Must conform to people's visual feeling and psychological impression

(2) Preparation before image processing
◆ According to the picture primary and secondary, necessary cropping
◆ Determine the size of the picture in the layout
◆ Determine the picture resolution
◆ Determine the picture color mode

(3) Image processing ideas
◆ First analyze the characteristics of the picture, the advantages to retain, shortcomings to correct; (such as: level level - normal, thin, thick stuffy, flat, come; Color - normal, partial color, special effect tone; Clarity - clear, fuzzy)

◆ The first overall adjustment ink, after local correction; (For example, when using mask for local processing, it is necessary to consider the characteristics of the surrounding environment to avoid distortion and incongruity)

(4) Image processing methods and skills
First of all: the level and contrast adjustment
* Black and white field calibration (Color Tool-Levels)
* Level Adjustment (Curve Tool -Curves)
* Correction of insufficient contrast (brightness/contrast tool)
* Correct dimming level (Shadow/highlight tool)
* Correct intermediate thickening (exposure tool)
* Correct Color bias (Color Balance tool)
Second: color adjustment
* Correct Hue and saturation (Hue/ saturation tool -Hue/Saturature)
* Enhance or reduce Color saturation (Elective Color Calibration Tool -Slelective Color) authentication
* Local correction of shading (Dodge, Darken and Sponge tools)

◆ Again: clarity adjustment
* Enhanced clarity (Unsharp Mask)
* Reduce sharpness (blur Tool -Gaussin blur)

Due to the poor whiteness of the newspaper, the lack of luster, the picture processing needs to pay attention to:
(1) The overall contrast is enough
(2) light tone is the main, dark tone is auxiliary
(3) Bright color printing accessories, basic color saturation
(4) Appropriate sharpening, clarity to do enough
