喷绘和写真中有关输出图象的制作标准

发布时间:2020-09-24 16:09:13 来源:http://www.jnpenhui.com

尺寸大小:
Size:
喷绘图象尺寸大小和实际要求的画面大小是一样的,它和印刷不同,不需要留出出血部分。在喷绘公司一般在输出画面后都有留白边的,一般情况都是留与净画面边缘10CM。如图你可以和喷绘输出公司商定好,留多少边用来打扣眼。价格是按每平米计算的,所以画面尺寸以厘米为单位就可以了。
The size of the inkjet image is the same as the actual picture size, which is different from printing, and does not need to leave bleeding part. In the inkjet printing company, there are white edges left after the output screen, and the general situation is to leave and clean the edge of the picture 10cm. As shown in the figure, you can agree with the ink-jet output company on how many sides to leave for buttonholes. The price is calculated per square meter, so the screen size is in centimeters.
图象分辨率要求:
Image resolution requirements:
喷绘的图象往往是很大的,应该明白“深在庐山不知庐山真面目”的道理。那喷绘图象也是这样,如果大的画面还用印刷的分辨率,那就要累死电脑了。但是喷绘图象分辩滤也没有标准要求,下面是我个人使用不同尺寸时使用的分辨率,可以参考:
The images of inkjet painting are often very large. We should understand the truth that "deep in Lushan Mountain, I don't know the true face of Lushan Mountain". The same is true for inkjet images. If you use printing resolution for large images, you'll be exhausted. However, there is no standard requirement for the resolution of inkjet image. The following is my personal resolution for different sizes
图象面积(平方米) 180无穷
Image area (square meters) 180 infinity
分辨率(dpi)
Resolution (DPI)
说明:因为现在的喷绘机多以11.25DPI 22.5DPI 45DPI为输出时的图象要求的,故合理使用图象分辨率可以加快做图速度。
Note: because most of the current inkjet printers use 11.25dpi 22.5dpi 45dpi as the output image requirements, the rational use of image resolution can speed up the drawing speed.
写真一般情况要求72DPI/英寸就可以了,如果图象过与大(如在PHOTOSHOP新建图象显示实际尺寸时文件大小超过400M),可以适当的降分辨率,控制在400M以内即可。
Generally speaking, 72dpi / inch is enough for photo realistic. If the image is too large (for example, the file size exceeds 400m when the new image is displayed in Photoshop), the resolution can be reduced to within 400m.
图象模式要求:
Image mode requirements:
喷绘统一使用CMKY模式,禁止使用RGB模式。现在的喷绘机都是四色喷绘的,它的颜色与印刷色截然不同的,当然在做图的时候按照印刷标准走,喷绘公司会调整画面颜色和小样接近的。
Inkjet printing unified use of cmky mode, the use of RGB mode is prohibited. Today's inkjet printing machines are all four-color inkjet printing, and its color is quite different from the printing color. Of course, when drawing according to the printing standard, the ink-jet printing company will adjust the color of the picture to be close to the sample.
写真可以使用CMKY模式,也可以使用RGB模式。注意在RGB中大红的值用CMKY定义,即M=100 Y=100。

You can use either cmky mode or RGB mode. Note that in RGB, the value of bright red is defined by cmky, that is, M = 100, y = 100.
图象黑色部分要求:
Requirements for black part of image:
喷绘和写真图象中都严禁有单一黑色值,必须填加CMY色,组成混合黑。假如是大黑,可以做成:C=50 M=50 Y=50 K=100。特别是在PHOTOSHOP中用它带的效果时,注意把黑色部分改为四色黑,否则画面上会出现黑色部分有横道,影响整体效果。
It is strictly forbidden to have a single black value in both inkjet and photo images. CMY color must be added to form mixed black. If it is big black, can make: C = 50 m = 50 y = 50 K = 100. Especially in Photoshop, pay attention to change the black part to four color black, otherwise the black part will appear on the screen with horizontal bars, which will affect the overall effect.
图象储存要求:
Image storage requirements:
喷绘和写真的图像最好储存为TIF格式,但是注意不可用压缩的格式。
Inkjet and photo images are best stored in TIF format, but do not use compressed format.
关于点数,视情况而定。喷绘一般30dpi,写真一般72dpi,如果画面大,可以相应缩小。我做过的最小点数是10dpi,300平方。再大的话,可以分几段文件作。写真一般不低于50dpi。关于点数小,画面并不会变模糊,而是会产生较强的锯齿,相反的,加大点数,拉大图片的话,就会变模糊,而锯齿少明显点。一般做的话,可以双管齐下,自行斟酌。
As for the points, it depends. Generally 30dpi for inkjet painting and 72dpi for portrait. If the picture is large, it can be reduced accordingly. The minimum number I've ever done is 10dpi, 300 square. If it is larger, it can be divided into several sections. Generally, the photo should not be less than 50dpi. As for the small number of points, the picture will not become blurred, but will produce strong sawtooth. On the contrary, if you increase the number of points and enlarge the picture, it will become blurred, and the sawtooth will be less obvious. In general, you can do it in both ways.
关于压缩格式,一般的喷绘公司要求是用tiff,cmyk格式。其实用jpg也未尝不可,但压缩比必须高于8,不然画面质量无保证。 对于原始图片小,拉大后模糊的情况,可适量增加杂点。
As for the compression format, the general requirement of inkjet company is to use tiff, CMYK format. In fact, it's OK to use JPG, but the compression ratio must be higher than 8, otherwise the picture quality is not guaranteed. If the original image is small and blurry after being enlarged, the clutter can be increased appropriately.
喷绘的话25-30点就够了我们公司是以色列的塞天使,和美国的威特上喷绘机的图最后点数是23.125(威特的).你做图时作大了点数上机子时也会把点数降下来.作图时最好用CMYK的因为喷绘和RGB显示还是有区别的.咱们不都是先给客户看小样才定图喷的吗?用CMYK出小样如果客户接受的话那喷出来也就没什么问题了
25-30 o'clock is enough for inkjet printing. Our company is Israel's zeyland, and the US's Witt. The final points are 23.125 (Witt's). When you make a large number of points, you will also reduce the number of points. It's better to use CMYK when drawing, because there is still a difference between inkjet and RGB display. Don't we all show customers the small sample before we decide to spray the drawing? Use CMYK to make the sample as follows If the customer accepts it, it will be OK to spray it out
机器是赛特3。2米的。我最小做过13。3的分辨率。330平米。 留5厘米白布。我这大部分安装都用30mm或25mm的方管,应该没什么问题的。 我想RGB的颜色应该没有CMYK的准。 我只做写真的才用RGB。
The machine is set 3. Two meters. I've done 13 at least. 3. 330 square meters. Leave 5cm of white cloth. I use 30mm or 25mm square tube for most of the installation. There should be no problem. I think RGB color should not be CMYK accurate. I only use RGB for portrait.
在PS把图放大到100%(实际输出尺寸),观看你的字体是否有锯齿,背景是否太划了,其他就根据自己的经验看了。其实背景不是太主要的,文字不要在100%显示下有锯齿才是真的哦~ 对了,有些字体放大以后锯齿严重,换其他的相似的字体好了~建议用方正的
In PS, enlarge the image to 100% (actual output size) to see if your font is jagged and if the background is too scratched. The rest is based on your own experience. In fact, the background is not too important, the text should not be jagged under 100% display. Oh, yes, some fonts are seriously jagged after zooming in. It is recommended to use square fonts
丝网印刷
screen printing
丝网印版的部分孔能够透过油墨,漏印至承印物上;印版上其余部分的网孔堵死,不能透过油墨,在承印物上形成空白,以丝网为支撑体,将丝网绷紧在网框上,然后在网上涂布感光胶,形成感光版膜,再将阳图底版密合在版膜上晒版,经曝光.显影,印版上不需过墨的部分受光形成固化版膜,将网孔封住,印刷时不透墨,印版上需要过墨的部分的网孔不封闭,印刷时油墨透过,在承印物上形成黑迹。丝印的墨层比较厚,色彩表现能力较差,如果想要得到较好的效果,可以将目数提高一些,最少要超过300目/英寸。制作时一般没有什么要求,能满足质量就行,不像胶印或凹凸印那样要求高。
Some of the holes in the screen printing plate can pass through the ink and leak to the substrate; the rest of the screen on the plate is blocked and can not pass through the ink, forming a blank on the substrate. Taking the screen as the support, the screen is tightened on the screen frame, and then the photosensitive glue is coated on the screen to form a light sensitive plate film. After exposure and development, there is no need for the plate The over inked part forms a curing plate film under light, which seals the mesh and prevents ink penetration during printing. The mesh of the part on the printing plate that needs to be inked is not closed. During printing, the ink passes through and forms black marks on the substrate. Screen printing ink layer is relatively thick, color performance is poor, if you want to get better results, you can increase the mesh number, at least more than 300 mesh / inch. Generally, there is no requirement for production, which can meet the quality requirements. It is not as high as offset printing or bump printing.
