The dream of a pre-press expert: CoPrA and ColorAnt at service for Scancolor
Scancolor Reprostudio GmbH was founded 25 years ago in Leipzig, Germany and employs 10 people. The company focuses on images, reproduction from slides, originales sometimes larger than 6 feet, digitalizations of copy dot prints, photo retouch, ICC profiling, photo laboratory, and large-format digital print, really aimed towards fine tuning.
Reproduction of high-quality images, may it be for a book, an exhibition, arts market or even for a museum. The amount of different, sometimes even exotic, kinds of output devices requires a color management which ensures constant and reliable quality. This know-how is used internally at Scancolor but also as an external consultant. Ralf Lenk is the Managing Director of Scancolor and simply loves the reproduction work. Many of his visions he already made a reality with his company but still he has dreams…
What is the pre-press expert’s dream?
After a long day with a motivational coach who sold me common sense for a reasonable amount of money, I’m still hearing his platitudes while drifting into sleep. Get rid of your boundaries. Try something big, something special. Spread the colors into the world.
Compressed into far too small color spaces the whole day, I start to mix the images in my dream, they are getting more colorful. I jump through a color space full of joy, get rid of the Uncoated and than the Coated color gamut and feel the new spirit of the enlarged color space. While slowly waking up again, I add some more fantasies about tools allowing me to edit them any time I want to.
Ping! This wonderful dream is interrupted by a new incoming email.
An advertisement from my software dealer Impressed with news from ColorLogic. Déjà-vu.
If it is really true what is written in this mailing, they have the product I was dreaming of.
A demo license ensures that it is not only a nice description of a possible solution but that it is in fact exactly what I was looking for – I am absolutely excited.
To be honest, a multi color separation is nothing really new. There was this software from Hell capable of scanning CMYK and RGB and print the result in 7 colors. Another solution was from Colorblind in the beginning of the 90’s, followed by Logo ProfileMaker, X-Rite i1 Publish etc. Special-color also offered some possibilities. With these options there are limitations and it is required to print large test charts for every color, or to define each and every setting but without any measurement data.
With the Multicolor license from CoPrA I am able to combine the measurement data from my CMYK plus the spot colors directly in ColorAnt, and even better – to modify them in any possible way. Whenever I print a spot color, I am able to consider that other spot colors may have the same characteristic, with only minor deviation. Every color can easily be changed by modifying the LAB (spectral) values and also be added and modified by using the tone curve values.
Especially with facsimiles, where several spot colors are not unusual, this helps to speed up the workflow.
The CMYK values can be modified should it be to adopt to a different color batch or to reproduce CMYK images even with some exotic color combinations or to standardize your workflow by using a defined 7-color set for all different spot color combinations, and so forth….The possibilities are endless…
The design of the software is very straight forward and self-explanatory, how awesome is that! The possibilities to adjust the measurement data are almost unlimited. I can decide to optimize measurement data automatically or define each and every different adjustment individually. Due to the visualization which is possible for most of the adjustments it is really easy to control the modifications.
If I don’t want to dive into the different settings, I simply choose one of the presets and I will optimize my result or I can tweak each and every little thing however I like.
It’s all about those “little things”. Who has the time to print a test chart over until it is really perfect? In ColorAnt, there is the possibility of using Tone values to render a chart which is not yet as perfect as if it could be. With those optimized data you can generate an error-free, perfect ICC profile without the risk of some minor errors in the measurement data ruining your whole profile. Very well thought, developed from experts, a solution which covers all your wishes.
The combination of CoPrA and ColorAnt is a “complete” package:
- You may generate charts and measure them inside the application
- Measurement data can be edited and optimized
- Several measurement chart can be averaged and everything can be visualized
In CoPrA, an ICC profile may be created based on this measurement data. Again, this can be edited and also inside the application applied to an image. Everything inside one solution which avoids possible errors during transmitting data. All of that is available for B/W, RGB, CMYK and spot colors which means it is applicable for any output scenario, should it be a photographical process, inkjet without a RIP, or any kind of printing process, such as offset, screen printing, flexo or gravure.
The possibility inside CoPrA to generate DeviceLink profiles is simply outstanding. Secure transformation from one color space into another while respecting the characteristics and requirements of the final output. Black generation, Exceptions, SaveInk and so forth are impressive and again, with the possibility to fine tune any kind of setting if necessary. The more exotic the task is, the more important are those exceptions.
Here is an example:
We process images photographically, which means we have to handle colors of a photographical coating. They are completely out of gamut of common printing colors. The yellow has a very high density but is a kind of reddish. A “normal” color management will change this into a lighter color and add some cyan to it. Methodically correct, but the result misses the density,therefore the picture has no longer has contrast. By defining the right exceptions in CoPrA the image will be calculated correctly even though primaries and secondaries are calculated with the maximum density.
Beside those special scenarios DeviceLink profiles simplify and optimize all of your daily work. Adjust coated to uncoated – generate a DeviceLink profile and everything is fine.
- Convert SWOP data received from the US to ISO coated V2 or FOGRA 51
- Re-separate incorrect separated data
- TAC is to high in the file
- Exact adjustment of data for the printer
- Adjust data for exotic printing material
- Calculate existing data for different printing methods
- Change coated data to other print standards
There is almost nothing which can’t be achieved with those “little magical tools”.
Software is much more than only the application itself. Consulting and support are also important topics and our dealer IMPRESSED and ColorLogic are simply outstanding in this area. Within a very short time frame all questions are answered on a top-notch level in a almost familiar and very friendly manner. If I could think of anything “beyond expectation”, it is with this software.
We are an independent, technology driven company that creates strong and productive relationships between our partners, clients and team.
