對于從事平面廣告設(shè)計的職場人員來說，有必要在設(shè)計制作環(huán)節(jié)，了解印前技術(shù)在宣傳單印刷設(shè)計中的地位與作用，了解印前技術(shù)工藝特征和相關(guān)知識?；诖?，本文介紹宣傳單印刷設(shè)計中應(yīng)注意的幾點知識。
For professionals engaged in print advertising design, it is necessary to understand the position and role of prepress technology in leaflet printing design, as well as the process characteristics and related knowledge of prepress technology in the design and production process. Based on this, this paper introduces some knowledge that should be paid attention to in leaflet printing design.
一、顏色模式
1、 Color mode
顏色模式，是將某種顏色表現(xiàn)為數(shù)字形式的模型，或者說是一種記錄圖像顏色的方式。分為:RGB模式、CMYK模式、HSB模式、Lab顏色模式、位圖模式、灰度模式、索引顏色模式、雙色調(diào)模式和多通道模式
Color mode is a model that represents a color as a digital form, or a way to record the color of an image. It is divided into RGB mode, CMYK mode, HSB mode, lab color mode, bitmap mode, gray mode, index color mode, two tone mode and multi-channel mode
設(shè)計者要注意顏色模式的設(shè)置和轉(zhuǎn)換。一般來說，設(shè)計者在RGB顏色空間中進(jìn)行設(shè)計創(chuàng)作，輸出時根據(jù)輸出目的進(jìn)行輸出設(shè)置或轉(zhuǎn)換。
Designers should pay attention to the setting and conversion of color mode. Generally speaking, designers design and create in RGB color space, and set or convert the output according to the output purpose.
(1)針對顏色一致性要求較高的包裝設(shè)計，設(shè)計者在RGB顏色空間中進(jìn)行設(shè)計創(chuàng)作，可嵌人RGB特性文件輸出，由印刷企業(yè)進(jìn)行CMYK模式轉(zhuǎn)換。
(1) For packaging design with high requirements for color consistency, designers can design and create in RGB color space, which can be embedded into RGB characteristic file output, and the printing enterprise can convert CMYK mode.
(2)針對顏色一致性要求不太高的商業(yè)設(shè)計，如海報、雜志等，可直接轉(zhuǎn)換成CMYK進(jìn)行輸出，轉(zhuǎn)換時注意CMYK顏色空間的設(shè)置。
(2) Commercial designs that do not require high color consistency, such as posters and magazines, can be directly converted to CMYK for output. Pay attention to the setting of CMYK color space during conversion.
(3)針對網(wǎng)絡(luò)或屏幕出版的設(shè)計，如宣傳單設(shè)計、電子雜志印刷設(shè)計，可直接輸出為RGB模式的文件，注意RGB顏色空間的設(shè)置。
(3) For the design of network or screen publishing, such as leaflet design and e-magazine printing design, you can directly output files in RGB mode. Pay attention to the setting of RGB color space.
二、圖像分辨率
2、 Image resolution
數(shù)碼圖像有兩大類，一類是矢量圖，也叫向量圖;另一類是點陣圖，也叫位圖。宣傳單印刷業(yè)務(wù)的流程設(shè)計和業(yè)務(wù)管理
There are two categories of digital images. One is vector graph, also known as vector graph; The other is dot matrix, also known as bitmap. Process design and business management of leaflet printing business
