印刷知识：海德堡印刷机变色问题的几个简单处理方法我们在使用海德堡印刷机的时候，往往在使用一段时后可能会出现印变色的情况，对于这一情况，我们广大的海德堡印刷机使用者往往无从下手，而且要花费大量的时和金钱来维修这一情况，针对这一情况，我向大家介绍几个本人人为比较有效的方法，希望在大家使用的过程中能够起到作用。

1．首先我们应该检查我们印刷在版面上的设计是否合理，比如把墨量比较大的图案（或者是四色网的叠加）放在拖稍位置，对于这样的版面设计肯定是不利于我们印刷出高质量的印刷的，我们应该把他们放在叼口位置，这样有利于叼牙对纸张的控制，更容易印刷出不变色的印刷。

2．如果已经出现了印刷变色的情况，我们不要开始就下印刷机本身的问题这样的结论，我们应该先在印刷机的外围寻找原因，我们首先应该使用放大镜观察印刷版上的网点，检查它是否已经出现的网点的变形，如果发现在印刷版上已经出现了网点的变形，那么我们应该对片子进行检查，排除在出片的时候的问题。

3．在我们排除了片子问题之后，我们应该检查墨路系统是否出现问题，检查墨路系统我们可以用很简单的方法，首先我们使用洗车水（可加水）将墨路彻底清洗干净，停车后我们应该检查墨路中是否有白色结晶的颗粒物存在，如果我们发现有这样的物质存在，那么出现的变色情况有可能是结晶物质堆墨尔生的印刷局部变色，这种变色往往更体现出来的刷局部色彩偏色。

在洗车后没有发现这些结晶物质，我们重启动印刷机，打墨到每一根墨辊，打墨结束后我们合上靠版墨辊和靠版水辊，检查压力是否达到标准，如果没有，我建议将所有墨辊压力重调整，已达到较好的状态。

4．在墨路系统没有问题后，我们检查水路的情况，调整好靠版水辊，计量辊，水斗辊，及窜水辊之的压力，特别要调整好中辊的压力，在自己技术不够的条件下中水辊在印刷过程中最好不要使用。

5．如果水墨路都没有问题，我们应该检查橡皮的衬垫是否是标准，我们建议衬垫的厚度应该为35丝，橡皮布最好是牌的带铝条的而且橡皮布最好是的。

印刷流程中的色彩管理(一）印刷流程中的色彩管理(一）色彩管理在各位的生产流程中，可能每一天都会面临到，只是在之前的流程中如何来设定的问题，譬如工具的选用，以及色彩的选用等，而我们在这边提出来的重点是如何针对各位在整个工作流程中，轻易的做到色彩管理。

首先，我们先从印刷厂中怎么样的去做色彩管理的一个架构来看：我们这次实际的去做了一个实验，所使用的工具包括：●上海印刷厂的罗兰五色印刷机700+Pecom●爱克发的色彩管理系统ColorTunePro3.02●海得堡的色彩管理系统PrintOpen3.0●爱克发印前流程管理系统Apogee●台湾巴而可屏幕及色彩管理系统●爱克发印前校样设备Apogee Sherpa43●标准光源D65灯箱在这样的一个架构之下，我们就产生一个印刷的色彩管理流程。

（一）在整个色彩管理流程中最重要，也是色彩管理最后想达到的目标，就是最后要印刷的印刷品，所以我们针对这个部分，必须要先做Printer Profile（印机的色彩描述档），为什么要先做Printer Profile因为我们希望我们色彩仿真的对象是根据最终要去交货的印刷品，先做Printer Profile这样才会有一个依据，因此在整个色彩管理流程中，印机的色彩描述档，必须要先去做，做完之后才可以往前、往下去做，继续推演每一个流程你应该去取得的一个参数。

所以我们做的流程是利用IT8-7/3的一个电子稿直接送进底片输出机，晒成版或利用CTP直接制成印版，在印刷机上利用一个标准印刷条件，这个印刷条件是依据SID（满版印墨浓度）、及DG（网点扩大）来控制的，这两个参数一定要先设定在一般工厂生产的常用值，在这样的设定下去求取印刷机的色彩描述档，而在IT8-7/3的原稿中共有928个色块，利用色度计去量取，就可以得到印刷机的色彩描述档。

（二）另外，我们在仿真印刷机方面利用喷墨打样机直接做出印刷机的打样，在这一个部分我们在喷墨打样机的SID、DG部分必须要先做一个「线性的校正」，让喷墨打样机符合我们印刷机所能印刷出来的色域，而这个「线性校正」所根据的就是之前所说的印刷生产的常用值，否则喷墨打样的样张就可能是印刷机所无法印刷的颜色，经过这样的流程之后，我们就可以得到Proofer Profile（喷墨色彩描述档）（三）屏幕是大家在看档案的一个依据，我们可以利用一些工具来做屏幕的色彩描述文件，它的主要结构都是利用LED的感光，透过滤镜来接收不一样的色彩刺激值X、Y、Z，产生屏幕的色彩描述文件，记录屏幕的色彩记录能力。

Assess • The assessments can be viewed in manyd ifferent ways on the screen or issued as a printedr eport. Color space comparisons between two sets of measuring data can be represented in two or three d imensions.Long-term analysis • Several sets of measuring data can be read in and compared. They make it possible to analyze color behavior over a longer period of time. It is therefore possible to document a quality standard and color fidelity is no longer a subjective sensation. Proof report • Quality Monitor supplies a report on the color accuracy of the proof. This report can be handed over to the customer in the form of a certifi-cate together with the proof.Measuring devices and testsThe programs of the Prinect Color Toolbox work with many of the leading spectral photometric and densito-metric measuring devices and support standard tests in accordance with ISO 12642, including ECI 2002, IT8.7/3 and IT8.7/4.Quality Monitor is the ideal tool for seamless process and quality monitoring.4elements, which are printed during normal production. Building on an ex-isting profile and the measuring data of the Mini Spots means that a p rofile adjustment can be calculated within a short space of time and is then al-ready available for the next set of plates.Any fluctuations related to the equipment can be recognized and smoothed out with a connectable profile smoothing. This makes Profile Tool the ideal tool for the creation of generic profiles to describe a printing standard.00.993.3615/01 e nHeidelberger Druckmaschinen AG Kurfuersten-Anlage 52–60 69115 Heidelberg GermanyPhone +49 6221 92-00 Fax +49 6221 92-6999 TrademarksHeidelberg, the Heidelberg logotype, Prinect and Mini Spots are registered trademarks of Heidelberger Druckmaschinen AG in the U.S. and other countries. PANTONE and Hexachrome are registered trademarks ofP antone Inc. All other trademarks are property of their respective owners. Subject to technical modifications and other changes.ICC output profiles for the proof • The creation of profiles for the proof is optimized in order to achieve the best possible color adjustment. The iterative proof correction makes it possible to achieve a level of accu-racy in the profile, which reduces the average colord eviation of the proof from the print to an absolute min-imum. An integrated color calculator converts spot colors to the CMYK values of the proofer. This means that the expanded color space of the proofer is fully utilized. The PANTONE® and HKS color tables are in-cluded in the software package.Color measurement and correction • The Profile Tool measures true spectral values in the color fields. All the desired values such as Lab, XYZ, CMYK or den-sity can easily be calculated from this. The program can therefore use values, which have been m easured once, in many ways. Optical brighteners in papers, which are interpreted by measuring devices as shades of blue and would therefore lead to errors in the pro-file calculation, are corrected by the Profile Tool on aspectral basis.Calibration and profiling with one proof run •N ormally a test sheet can be printed first to compile an ICC profile, if a process calibration has been carried out previously. The Profile Tool can also calculate good pro-files from the measuring data of an uncalibrated print taking account of the calibration data of C alibration Tool. This means it is no longer necessary to print and measure test sheets repeatedly, which is time-consum-ing. This saves not only time and materials. It also helps to cope with color management in the overall printing process rapidly and with certainty.Device Link Profile • In many cases it is necessary to align the print customer’s documents directly with one’s own production environment. Profile Tool has the functions necessary to do this. This also includes UCR/GCR functions in order to use less colored ink to achieve the same impression of color. This means that the gray balance can be stabilized and color fluctua-tions avoided. In addition, it is possible to limit the maximum inking of every object, whereby the color ad-justment on the printer can be managed more easily and quickly. Fine-tuning is generally carried out with device link profiles. The Profile Tool creates extremely sophisticated device link profiles for use in the Prinect workflow. There is no need to buy an expensive addi-tional solution for this purpose, as all the necessary functions are already integrated into the profile. P rocess conversions can therefore be carried out from one CMYK printing process to another with a high level of quality.Separation of up to seven colors • By using theo ptional multi color extension, it is possible to produce color separations for 5-, 6- and 7-color printing. The inks for this can be selected in a sequence, which makes sense in colorimetric terms. This means that frequently used color models such as Hexachrome® or HiFi Color are supported to the same extent asc ustomer-specific models.Profile Tool creates extremely sophisticated device linkp rofiles for use in the Prinect workflow.2Calibration ToolCentral management of all the calibration data • Calibration Tool makes it possible to create and cen-trally manage all the calibration data for the lineari-zation and process calibration of CtP platesetters and direct-imaging presses. The tool supports both thel inearization of platesetters and the calibration of the entire process section right up to printing.Thanks to Calibration Tool it is possible to set up as many spot colors in one data set for process calibra-tion as desired. This means that a data set can con-tain either all the process colors or be ap p lied indi-vidually for each separation.A central data pool • In a company with several plate-setters the curves for each output device can easily be arranged and managed. If several platesetters of the same type and using the same materials are de-ployed at the same time, Calibration Tool can be used to organize a central data pool. It is possible to feed the RIP imagesetter stations with the right curves for each job from there – creating ideal conditions for consistent quality at each station.Simple application of calibration curves • The print parameters such as type of paper, ink used, solid tint densities and printing press are stored with each cali-bration curve. Calling up the right curve is controlled by indicating these parameters. Calibration Tool offers only those curves, which are actually suited to the print parameters in the job. This not only makes o peration easier, but also helps to avoid errors.The actual dot gains are generally described by process standards. A range of standards is already provided with their dot gain curves. It is possible to define one’s own process parameters individually for corporate standards.The resulting process curves can be smoothed out in order to compensate for measuring errors.In addition, Calibration Tool offers numerous editing functions to compile new curves, which are superim-posed on an existing calibration. If one parameter changes, then a test sheet does not have to be printed and measured from scratch. All that needs to be done is to calculate the changes using the existing curve.A new, adjusted curve is then available for the next set of plates. Rapid calibration with Prinect Image Control • The interaction of Calibration Tool and Prinect I mage Control color measurement system provides superb rapid and precise calibration with Mini Spots. The mea s uring elements are assessed in one go and a fter a few seconds the measuring data are available for a calibration adjustment.RIP-independent installation • Calibration Tool does not have to be installed on the RIP station. It is also possible to set up a separate calibration station in which the curves are measured and compiled central-ly for the connected RIP imagesetter stations. By ad-ditionally installing Profile Tool, this station can beu pgraded to a central color management workstation within the company.Quality MonitorSeamless process and quality control • Print shops are increasingly applying for certification to a quality standard. This is associated with the requirement of being able to provide evidence of continuous compli-ance with the standard. This is where you need Quality Monitor: It is the ideal tool for seamless p rocess and quality control. It provides every print shop with de-tailed analysis results.Both printing companies, which already document the high standard through their certification, as well as companies, which are just starting out with standard-ized printing, can demonstrate the high quality of their work and present it clearly at any time with Quality Monitor. Detailed reports, even compiled over a longer period of time, therefore serve both as documents for control as well as evidence of reliable production at a consistently high level.All the decisive tasks of process supervision andm onitoring the proof and print can be carried out with Quality Monitor:Measure • Numerous keys, linearization strips and entire test sheets can be measured out with spectral photometers, densitometers or plate measuringd evices.Compare • Quality Monitor permits comprehensive comparisons between two sets of measuring data, e. g. the deviation between the proof and print or print standard or the deviation in a print run.3。

PRINTING FIELD 2020.05数字印刷是将数字图文信息直接转移至承印物上的复制过程。

整个过程接近于打印，故其色彩管理一般是按照打印机色彩管理流程进行的。

一、操作方法色彩管理系统的工作过程通过所谓的“3C”进行控制，即设备校正（Calibration）、特征化（Characterization）和色彩转换（Conversion），代表了色彩管理技术实施的三个重要环节。

本文按照这三个步骤进行数字印刷机的色彩管理操作实践。

其中用到的相关设备、测试工具软件和色表如下。

1.数字印刷机：海德堡Versafire EV；2.测试设备：EFI ES 2000，爱色丽i1 isis2 XL；3.测试色表：IT8.7/4Randomisis（A3）.pdf、CI_GrayConM_i1_FOGRA51_v3_15mm.pdf；4.对比参考文件：Fogra51Random.txt；5.打印和测试软件：PrinectCockpit，Color Toolbox。

二、操作过程1.设备校正数字印刷机的校正（线性化）是保障数字印刷机处于稳定状态的重要操作。

操作方法是利用数字印刷机打印内置的测试文件，利用分光光度计测试文件中不同色块的密度值，跟目标值比较，然后进行自动补偿和修正。

数字印刷机的校正实质上是在其他参数确定的前提下，对某类纸张进行校正。

海德堡印通DF E流程中定义了多种纸张，常用的有光面纸、磨砂纸和普通纸（非涂布纸）三种。

首先，将需要做校准的纸张放到纸盘中，在Prinect Cockpit屏幕右上角选择打印管理器，在打印管理器界面选择校准标签。

在预定义的校准数据中选择接近要校准纸张的数据作为目标数据，用复制的方法建立一个新的校准数据。

在这里不能选择新建，否则就没有目标数据了。

另外不要复制结尾带有（日本纸）标记的预设数据，因为这些预设值仅针对日本纸设定。

接下来设定校准的名称，校数字印刷机色彩管理操作实践于士才则应循环上面的操作直至符合要求。
