Gain access to helpful tips and advice to enhance your print materials.Online OrderingOur custom-built online ordering storefronts allow you to organize and maintain your company marketingmaterials. Your color profile can be built into customizable templates such as business cards to ensure optimum brand color output.Pantone ColorThe Pantone Matching System (or PMS) is a standardized colormatching system used primarly in the printing industry. Each Pantonecolor is assigned a number used to identify that color in designsoftware and printer platforms.Traditionally, printing presses would match Pantone colors by mixingspecific combinations of ink. Since digital printers produce ink onpaper by CMYK color process, Pantone colors could not always beachieved. But due to recent advances in digital print technology, thePantone color matching system can now be combined with the powerof digital, on demand print.CMYKDigital printers use a combination of four toner colors (Cyan,Magenta, Yellow, and Black) to achieve print on paper. CMYK colormode should always be used for print documents.RGBRGB (Red, Green, Blue) is a color mode which uses combinationsof Red, Green, and Blue to create color on screen. There are RGBcolor combinations (particularly very bright colors) that cannot bereproduced using CMYK process. RGB color mode should only beused for screen viewing purposes, such as website creation.3C MY K R B Brand ColorsSuccessfully “owning” a color is a big deal. Your company brand color is part of your identity and it’s important to provide your audience with a consistent family of documents to create brand awareness.Brand colors are typically the colors used within your company logo (which is usually one or two colors). If your company has a brand guide, your brand colors should be outlined there. Often a company will select a Pantone color and a CMYK value equivalent. Both of these color values are essential to the color matching process and should be provided to DigiCOPY .If your company does not have a brand guide, the person who originally designed your logo should be able to provide brand color information.Optimum ColorOptimum color ensures that your brand color is reached on a consistent basis. Note that all of the following are factors in reaching optimum color output for your print project.4ColorSync Guide BookPantone ValuesPantone color values must be called out in native files for all applicable graphics and text. The use of Pantone values is the only way to ensure your brand color is matched consistently.File Creation SoftwareAdobe Illustrator, InDesign and Photoshop are the only softwares that support Pantone color values. Thus, your documents must be created using one of these programs. For step-by-step instructions on how to call out Pantone values using each of these programs, see page 6.Cut SheetsOur color matching software integrates with equipment that outputs cut sheets such as 8.5x11, 11x17, 12x18, and 13x19. Products that fall under this category include business cards, postcards, brochures, flyers, books, magnets, and small posters.PaperSubtle differences in paper can greatly alter the appearance of color print. When selecting a paper foryour project, choose a white paper to achieve optimum color output. However, keep in mind that even the difference between a coated or uncoated white paper can change how color print will appear.Close Match ColorClose match color is not guaranteed to be an exact match to your brand color. Note that if any of the following applies to your print project, you can expect close match color output.CMYK ValuesCMYK color values are called out in native files for all applicable graphics and text.File Creation SoftwareMicrosoft Word, Excel, or Publisher support CMYK color values. For step-by-step instructions on how to call out CMYK values using each of these programs, see page 7.Large Format & Special ProductsLarge format and special product printing use different output processes than our digital presses. Therefore, close match color applies to these products, which include large format signs, banners, plastic cards, CDs and DVDs.PaperIf an off-white or colored paper is used, it may alter the look of color print.5Adobe Creative SuiteCorrectly specifying color information in your files is critical to accurate color output. Follow these guidelines when using Adobe Creative Suite software to specify Pantone values in your document.Adobe InDesign Step 1: In the Swatches panel, select “New Color Swatch”From the Color Mode drop-down, select “PANTONE + Solid Coated”.Type the Pantone number in the box provided and click “Add”.Step 2: Select your text or objectFrom the Swatches panel, select the swatch that you just added to applyto your text or object.Adobe Illustrator Step 1: In the Swatches panel, select Open Swatch Library > Color Books > PANTONE + Solid CoatedIn the “Find” field, type the Pantone number in the box provided and select“Add to Swatches” from the upper right drop-down.Step 2: Select your text or objectFrom the Swatches panel, select the swatch that you just added to applyto your text or object.Adobe Photoshop Step 1: Select your text or object and click the Color Picker icon Step 2: Click the “Color Libraries” buttonFrom the “Book” drop-down, select PANTONE + Solid Coated.Type the Pantone number in the box provided.Click the “Picker” button and then select “Add to Swatches”.You will be prompted to name your swatch if desired.You can now select your swatches from the Swatches tab.6ColorSync Guide Book7Microsoft Office Pantone colors are not supported by Microsoft Office software. However, specifying CMYK equivelants for your brand colors is critical to close match color output. Follow these guidelines when using Microsoft Office software.Step 1: Select your text or objectStep 2: Open the Color Selection window Click on the icon for “Font Color” (if text isselected) or “Fill Color” (if object is selected)drop-down and select “More Colors...”Step 3: Click on the “Color Sliders” icon (second fromleft) and make sure “CMYK Sliders” is selectedfrom the drop-downEnter the appropriate CMYK values Add the color to your swatchesClick and drag the color bar at the top of the windowdown to the swatch bar at the bottom of the window.Click “OK”.

色彩管理详细概述色彩管理是一种使用计算机和软件进行处理和管理色彩的技术。
它旨在确保在不同的设备、平台和媒体上,以一致的方式呈现色彩。
色彩管理非常重要,因为色彩的准确呈现对于许多行业和应用来说至关重要,例如印刷、摄影、设计、网页开发等。
色彩管理的基本原理是通过创建一个基于国际标准的色彩空间来描述和记录色彩。
最常用的色彩空间是RGB(红绿蓝)和CMYK(青、洋红、黄、黑)。
RGB色彩空间广泛用于显示器和数字摄影,而CMYK色彩空间则主要用于印刷。
在色彩管理中,一个重要的组成部分是色彩配置文件。
色彩配置文件是一种描述特定设备如何呈现色彩的文件。
它包含了设备的色彩特性和色彩空间。
每个设备都会有自己的色彩配置文件,这样可以校正设备之间的差异,确保一致的色彩呈现。
色彩管理的流程通常包括以下步骤:1. 校准设备:首先,需要校准每个设备以确保其准确呈现色彩。
这通常涉及使用校准仪器和软件来调整设备的设置。
2. 创建色彩配置文件:接下来,需要为每个设备创建色彩配置文件。
这通常是通过使用色彩管理软件和校准装置来完成的。
该软件将收集设备的色彩特性,并创建一个描述该设备色彩空间的配置文件。
3. 转换色彩空间:当需要在不同的设备和媒体上呈现色彩时,可能需要将色彩从一个色彩空间转换为另一个色彩空间。
这可以通过色彩管理软件来完成。
4. 预览和校对:在进行最终输出之前,可以使用色彩管理软件预览和校对色彩。
这可以帮助确保色彩在不同设备上呈现一致。
5. 输出:最后,可以将色彩管理的文件输出到所需的媒体上,例如打印机、显示器或互联网。
总体而言,色彩管理是一个复杂的过程,需要正确的硬件和软件工具,并确保准确的校准和配置。
通过色彩管理,可以实现在不同设备和媒体上一致和准确的色彩呈现,从而提高工作效率和减少错误。
色彩管理在不同行业和应用中都扮演着重要的角色。
以下是一些具体的应用领域和如何使用色彩管理的示例:1. 印刷和出版业:在印刷和出版业中,色彩准确性至关重要。
调色软件达芬奇中Color management的设置和基础运用色彩空间、LUT、Color Management基本概念由于篇幅限制,本文暂时没有时间来深入解释色彩空间的概念。
这里先做一个非常简短粗糙的概括。
Color Management就是从一个色彩空间到另一个色彩空间的转换。
摄影机的色彩空间是它的传感器能够捕捉到的色彩和对比度(具体概念参见文末注脚详解)。
消费级摄影机的色彩空间较小,高端摄影机的色彩空间要大得多。
摄影机传感器由于制造商不同而五花八门,同时伴随着技术不断进步,摄影机的色彩空间也多得令人眼花缭乱。
显示器(电视屏幕、显示器、电影放映机等)的色彩空间,是显示器所能再现的色彩范围和对比度。
显示器的色彩空间是由国际标准定义的。
广播电视的标准色彩空间是Rec709 Gamma2.4,电影院的投影是P3-DCI。
当摄影机色彩空间和显示设备色彩空间相同时,不需要任何转换。
很多采集设备,包括智能手机、单反、甚至一些专业电影摄影机,它们都记录在Rec 709 Gamma2.4的色彩空间中,因此不需要对它们进行Color Management转换。
为了充分发挥摄影机的性能,高端摄影机的色彩空间都比Rec709 Gamma2.4和DCI-P3更大,解决这个问题的方法就是使用LOG编码。
LOG本质上是一种为保留摄影机全部色彩空间和最大动态范围的方法,然后需要用一种方式将LOG素材转换为显示色彩空间,比如通过LUT,或者通过Color Management(色彩管理)。
LUT通用性强,使用方便。
但是LUT的精度是有限的,LUT通过一个输入和输出值数量有限的表来将一个大的色彩空间转换为一个小的颜色空间,这个过程在理论上信息精度是削弱的,当然以人眼的观看精度是几乎是无法察觉的。
Color Management则不一样,它使用的是精准的数学公式来进行转换,因此信息是有数学般完美的精确。
达芬奇中的Color ManagementColor Management应用于整个项目,所以首先需要在项目设置中激活它。

If you’re unsure about the benefits of Color Management for your business, Color Conformance and Assistance provides an ideal way to “test drive” what consistent color management can help you achieve in output quality and financial savings. Best of all, Ricoh experts can provide these services across any device, no matter the manufacturer.• • • •The benefits add up quickly:1. Ricoh InkSavvy for Ricoh high speed Continuous Feed Printers InkSavvy is an ink savings software tool exclusively for Ricoh Continuous Feed customers who want to save ink—and money—without sacrificing image quality. This solution allows operators to save ink by utilizing GCR (gray component replacement) in which parts of cyan, magenta, and yellow are being replaced with black ink, without a degradation of image quality. Depending on the files being printed and the amount of ink used, InkSavvy can save up to 30% of ink while keeping the image quality unchanged.Reducing the overall amount of ink on paper allows for faster drying times, leads to faster post-processing and finishing, and ultimately means faster turnaround times. Metamerism, the effect in which printed output appears to change based on the lighting it’s being viewed under, is dramatically minimized when utilizing intelligent GCR. This leads to fewer complaints about perceived color mismatches with end-customers who don’t have access to industry standard lighting (D50). Ricoh color experts provide customized, on-site implementation based on the user’s specific environment and needs, ensuring the best possible return on investment and full realization of the intended benefits. Savings are naturally dependent on the types of print jobs printed, and overall amounts of ink used per month.2. Ricoh High SpeedInkjet Color MatchingThe Ricoh high speed inkjet color match bundle isa software and services package to simulate the output of Ricoh’s high speed inkjet devices on a Ricoh cutsheet device.This allows Ricoh high speed inkjet customers to utilize other printers in the organization to simulate the output of inkjet. It enables short runs, reprinting individual pages, and hard copy proofing without disrupting production on the high speed inkjet printers.Simulating VC or IP color on short-run capable devices also enables customers to print accurate proofs on different types of paper. This eliminates the need for time consuming paper changes on high speed inkjet printers when only a proof or sample print is required.A color matched, secondary print system (Ricoh cutsheet toner), produces similar looking output without the need for long run-up times and web changes (paper changes).Ricoh toner devices can print on specialty media and even envelopes. Color matching those printers to a Ricoh high speed inkjet printer allows for the creation of color matched output on a variety of media. This could include trans-promo or direct mail with company logos and other imagery that match those on the envelope it’s being mailed in.Professional implementation includes all tools and training required to enable the Ricoh toner device to function as a proofing and re-print printer. Following implementation, you can maintain the color matched system yourself without the need for follow-up services. However, if you prefer, our Color Assistance Services are always an option.Advanced Implementation Services Maximize your return on investment on essential equipment from day one.

锐彩 RIP 色彩管理指南
锐彩V4.0 中文版
第一章 准备工作
打印机准备
1. 测试打印机,是否有堵喷头现象,如果堵喷头,不可以做色彩管理.
2. 纸张准备,长度:10米到20米;宽度:1米或1米以上.
3. 墨水最好是已经打印一段时间的,新墨水最好多清几次喷头,多打印一些图片后再
做色彩管理.
4. 电脑最好有10G 空间,内存大过512兆,安装有防毒软件.
推荐选择Eye-one ,在打印机的线性化和做纸张ICC 部分都可以使用.做纸张ICC 部分
可以使用ProfileMaker 或MonacoPROFILER.
这里主要介绍使用锐彩软件的色彩管理.
安装好锐彩(UltraPrint),在电脑USB 口上接好eye-one,自动搜索驱动,锐彩带有eye-one 驱动.
注: 如果是之前就装好的锐彩软件,请确认打印模式是”通用模式”.
图-1
仪器和软件准备
第二章色彩管理概绪
一. 为什么要做色彩管理
1. 不同的机器,墨水,喷头,pass都可能影响色彩的还原性.
2. 色彩管理的最终目的是让色彩在不同的设备上更好的还原.
3. .曲线记录并校正了此条件下色彩的差异.
二. 几大重点
1. 首先得截好墨,保证不会於墨,这点很重要
2. 调好CMY混和及单黑K的主体过渡.这步会影响整个画面的质量.
3. 最后再调偏色,浅色参考打印出的CMY灰平衡条调节,深色参考100%色块调节.
注意: (上面每一步都将影响下一步的调节)
第三章锐彩色彩管理的使用
密度曲线制作
1.曲线的选择———在“设置”菜单中选择“色彩管理”选项,进入色彩管理界面:
注:‘打印机选择’框内是已经添加的打印机,‘曲线’框内是当前打印机对应的已创建的曲线.
2.创建新曲线———点击“创建新曲线”,进入参数设置:
注:在这里设置“介质类型”、“色彩组合”、“精度模式”、“PASS”.然后点击“下一步”进入墨量设置.
六色
浅色设置:如果是做6色曲线,则会弹出浅色设置界面,在这里对浅色进行设置,设置后点击‘下一步’.
点击“下一步”进入线性化校正:
置曲线名.特别注意打印前曲线选项一定要是Untitle即本次的曲线.
墨量检测图
注:如果墨量太浓的话,有必要进行截墨,点‘打印墨量检测图’将打印一个墨量的检测图,用于判断墨量的多少.
截墨量说明:
1.单色
一般情况下,青、品、黄、墨单色是不用截的,除非是在墨水特别浓的情况下,
四色混合(四色通道)已调到了300以下还有於墨的情况,这样才考虑到截单色.截
单色后将影响到两色、三色、四色的通道,所以截完单色后还要打墨量检测图来
看看其它通道的墨量.
2.两色通道一般不用截
3.三色通道根据四色通道来截墨,为保证表达的色彩更丰富应该尽量少截,但也应保证三色通道到四色通道要有一定的色彩过渡,建议用四色值减去40得到三色通
道值.
4.四色通道是控制於墨的关键,为保证表达的色彩更丰富,在保证不於墨的情况下应该尽量少截.
截墨的时候需要注意:
单色墨量可根据需要相应的进行调整.双色墨量一般不截,三色墨量一般要少截,四色按需要截墨,保证不堆墨,不於墨即可.注意在三个色彩通道(300%)跟四个色彩通道(400%)应有40的差值,[例三个色彩通道为270%,则四个色彩通道应不少于310%]保证基本的过渡.建议:截墨量这一关,主要是看四色墨量,一般主要截四色.
3.线性化校正———分三次校正,每一次的流程都是一样的.向导会引导你完成三个
流程.
每一次操作:
1.点击"打印校准图"在机器上打印出校准图,待图稍干后剪下来,等图片干透后,开始做扫描测量.
2.在此之前接好eye-one程序会自动"仪器校准",如在此步接上eye-one请手动点击"仪器校准"进行扫描仪校准.
3.对照向导上的色块图进行扫描,扫描顺序为青、品、黄、黑.从浅到深.程序会记录对应结果.
4.扫完四条色块后点击查看曲线,如"实际曲线"较平滑时,进行下一次扫描.不平滑时重新扫描不平滑的色块,或在曲线微调中手动调整使其平滑.5.保存,进行下一次校正,直到第三次完成保存(强烈推荐完成三次校正).
注:扫描时尽量挑色块中比较均匀的地方扫.扫错的色块条可以重新选定再扫,如(青色扫错了,可以选定青色条,再重扫).对于有些扫描不过的色块,可对它进行“单点测量”.
6.查看曲线———点击‘查看曲线’按钮,将出现3个线性图:
第一个图:原始曲线图(未进行校准的实际曲线),若该图曲线基本像一条直线,那么说明本次曲线已校正完毕.如果非直线,那么你需要继续进行线性化操作,直到曲线
基本像一条直线.
第二个图:校准前的曲线.
第三个图:对第一幅图校准后的.
最后点‘保存’按钮,保存曲线,这是程序将提示是否继续校正或者结束校正,如果继续校正的话则需要重复上面的步骤,即,打图,扫图,微调.推荐进行线性化校正的次数不超过3次,除非墨量太过浓重.
第二次扫描结果:第一个框中的图始终不变;第三个框中的图将移到第二个框中;第三个框中显示当前本次扫描的结果.以后每次扫描的结果,都跟第二次扫描一样变化.
5.打印灰平衡检测条———更精确的调整色彩,看是否过渡均匀,有无偏色.建议初
级用户跳过此过程.
点击"打印灰平衡检测条"在机器上打印出灰平衡检测条.
过渡条图
调节灰平衡主要看CMY三色混合的过渡条(图左边下面第五条).
上面标了0 到100,分别对应CMY曲线上的0%到100%.理论上,灰平衡应该是灰的,所以如果在某个段上显示出其它着色,证明CMY没有达到适当的比例,这时在曲线调节中把偏色的曲线对应的点上下拉动.保存后再打图,直到达到理想的灰.
这里需要注意的是:
1.在没有把握的情况下一次不要调太多的点,也不要大幅度的调动.
2.根据三色互补,例如:30的地方偏红,您可以在M的曲线30的点向下拉,也可以在C和Y的曲线30的点同时向上拉.这要根据墨水的情况而调,像低Pass低级精度这样的情况打出来就可能会浅,这时就应该用后一种方法.
3.为保证过渡均匀较好,曲线也应该平滑.单个点不能调动太大的幅度,如有必要可把附近的点也同方向调整,以保持曲线的平滑.
6.曲线命名,保存结果.
新做的曲线保存时应该改成跟原曲线一致的名称,曲线标识(如HS)、颜色(如4color)、精度(如180x540)、Pass(如4pass).以保证在使用时软件可以自动匹配曲线.
如原曲线存在,请把原曲线备份.
8. 在曲线管理器中将看到保存的曲线.
修改曲线
1.在此可以打印墨量检测图进行墨量上限修改,曲线微调,打印过渡条检测图.曲线修正:在这一步,可以通过打印色条(过度条)来作为参考,微调曲线,或者整体调整颜色.在使用整体颜色调整的时候需要注意曲线调整后需要到曲线微调对话框,再稍微修补一下曲线,使曲线更自然,不会出现跳变.
2.修改完后保存退出.
* 曲线微调注意事项:
1)、不建议作大幅度的调整,具体调整幅度,是打印过渡条及打印图片效果确定;
2)、注意曲线整体平滑度;
3)、中性灰过渡条没有明显的偏色;
* 色彩曲线调整经验值:
1)、如果打印出的图像发黑,可以适当降低单黑 50%以下出墨量,CMY 三色50%也可以适当降低;
2)、如果打印出的人物图发黄,可以适当降低40%以下的黄色墨量;
3)、如果打印出的图像整体发灰,可以适当增加60%以上黑色出墨量;
4)、如果打印出的图像不够饱和,可以适当增加60%以上的 CMY 三色出墨量;
曲线重命名与删除
1.输入新的曲线名
2.删除曲线———选择要删除的曲线后,点”删除曲线”.
注意:删除后不可还原,请谨慎操作.
导入与导出曲线
1.导出曲线->把本打印机已有的所有曲线保存到其它地方.
2.导入曲线->导入其它曲线到本打印机.。
