creating consistent color.

New technology helps ink manufacturers to meet the manufacturer\'s demand for strict tolerances, and color has become an important asset for identifying products.
Shoppers around the world know Coca
There are countless products such as Coke red and Teide orange.
Companies that produce these products have a stake in protecting the color quality of the packaging.
These colors must be consistent, no matter what substrate it is on, no matter what can it be, a label, a pointof-
Purchase displays, cartons, advertising materials, clothing or other applications.
Printers and their customers expect colors to match their specifications and need to be constantly
Tightening tolerance for Inkmanufacturers.
Human eyes are no longer considered sufficient to judge the color.
Today, there are new technologies that can complement and improve the ability of the eyes.
Customers expect the same color.
If a person walks through the aisle of an agricultural store and sees two products of different colors, they may be worried that one of them is not fresh.
Companies that create products also expect accuracy.
LainPike, global product manager at X-said: \"The company wants to protect brand awarenessRite, Inc. \"Coke hasT-
Shirts, cartons, cans, advertisingof-
Buy monitors and trucks and they want the same color.
\"I would say that there is a growing interest in color consistency,\" said Terry Downs, color communication business manager at Datacolor International.
\"The term I use is \'protect brand asset \'.
\"These companies have invested heavily in developing their brand\'s association with specific colors,\" he said . \"Downes.
\"Tides are a good example ---
You may see a box or regeneration container with a printed label and they want the same color.
As we all know, the color of Tide is orange. whether it is a plastic container, a printed carton or a printed label, Tideorange should be damp orange.
\"In certain sectors of the printing and packaging industry, customers are very concerned that the color is absolutely accurate on any substrate,\" said Don Roworth, manager of color effective Limited.
For example, Sir.
Roworth pointed out that the ifa packaging color of frozen peas is blue, and people will tend to avoid this situation.
\"Several trends have led to a greater demand for color consistency: the global printing market, the ability to purchase printing around the world;
Industry trend to control ink density according to \"quantity by quantity (
Luminosity method);
Reduce costs and raise awareness of color measurement techniques, \"says Richard M.
Digital imaging and color reproduction based on graphic art research scientist Adams II (GATF).
Hal Goodall, director of marketing services at Hunter Labs, said: \"There is a greater demand in today\'s market and consumers expect higher quality . \".
This includes the consistent color of printed materials including packaging and containers.
\"Tolerance is a key aspect of color consistency because more technical measurements such as CIELAB are used to confirm that the color does meet the customer\'s specifications.
\"There are more and more customers who require us to meet the instrument specifications or matching, some of which are very tight tolerances.
\"When setting tolerances, the proofing system and inventory must be taken into account and the differences that can be visually seen,\" said Walter F . \"
Zawacki, technical manager of color and cardboard PDQ research, Flint Ink Corporation, member of the national printing Ink Research Institute (NPIRI)
Color task group.
\"The Task Force studied the common proofing methods for single sheet and concave printing in the first study, and the hot sleeve and Flexo were studied in the second study,\" Mr. Zawacki said.
\"For example, samples of the same ink lot and proofing stock were sent to the laboratory using sheetfedinks.
Both laboratories prepared prints using the Prufbau and joe proofreader.
We printed 10 photos in a row at the same target density, selected one as a \"standard\" and compared the other photos with it.
The total range of the cielab de * values of the 10 copy proofs varies from low to 0.
As many as 25 to 4.
There are 6 units depending on the proofreading method, ink color and the cardboard pallet display used.
The DE * value is from 0 even if Prufbau is used. 25 units to 1. 20 units.
Realistic color tolerances can only be set after determining the proofing method, inventory and the normal level of change that the operator may produce.
James Fusco, technical manager at Paul N, said: \"The supplier does not want a color change between batches . \". GardnerCo.
\"The colors everyone sees are a little different.
Our customers are looking for hard data that can quantify colors.
Instead of saying it\'s blue, they want to say what the values of L, A, and B are.
The instrument frees the user from the quality control and quantifies the color.
That\'s the bottom line.
\"The development of color test color measurement is used for quality control, formulation, specification and communication purposes.
From the human eye to the density meter, from the color meter to the light meter, the color measurement has changed over the years.
Each method has the advantage of measuring colors, but recent developments offer a better chance of accuracy. \"Portable hand-
Handheld color measuring instruments from density-
Rice introduced in the 1950 s to be \"affordable \"(ca. $10,000)
The spectrometer introduced in the early 1990 s for desktop splitter (ca. $1,000)
\"Free today . \"Adams said.
\"Although the eye is good at color discrimination, it is not good at color memory, so the importance of the instrument.
\"The eye is one of the best color difference sensors in the world, but if the product is not side by side, it cannot do anything with absolute color,\" said Mr. Downes.
Color cannot be measured by the density meter.
It can measure the amount of ink on the cardboard pallet display and is very good for pressure control.
\"One of the really important trends is the use of the splitter . \"
Don continued.
These allow you to measure color and density.
The trend that is taking place is to supplement or replace the density meter with a splitter. \" Mr.
Pike pointed out that there are many different ways to measure colors.
The density meter uses a logarithmic scale to measure the density to evaluate the change in color level and color level.
The color information is measured in three ways: tone, value (
Light/dark), and chroma (
Saturation/dull). Mr.
The splitter uses values of 16 to 32 or more to measure the reflective properties of the color/media combination, Pike said.
They are used for strict specifications of color and substrate, the transmission of color marks, and ink color formulation.
There can be 0 in a metering meter [degrees]/45[degrees]geometry (
For a relatively smooth surface), or d8[degrees]
Sphere Geometry (
For rough or textured surfaces).
\"There is a reason to do all this,\" he said . \"Pike.
\"These three are important for measuring cardboard PDQ inks.
The eye is the best color tool but it has no memory and is not digitalThis is subjective.
Everyone has different opinions.
Some people are blind. fatigue is also a problem.
The density meter measures the amount of light reflected.
It calculates the density value and you can do some rough color analysis with it.
\"An absolute color value can be specified by the splitter . \"Pike said.
\"It uniquely identifies the exact reflection of the acolor and the substrate combination.
The print of the ink has a great influence on the color.
One of the main applications is to calculate hue, which allows people to identify if the color is different before the color is pressed.
The lab is a good quality control measure to determine if it is the correct tone, intensity and color level.
You can also use it to test the density values.
Can also be used to prepare ink color.
They look at the actual spectral data and use a specialized ink recipe software that provides the recipe.
Science tells us what you need.
\"The exact nature of the splitter provides the power to form more stringent tolerances.
\"Everything is read in luminosity, so you have more strict control,\" said W . \"
Lide Wickline CDR pigment and dispersion.
\"This forces us to better control the production process of pigments.
We just mixed our three primary colors a few years ago and added the shader to it.
It is good to the naked eye, but not in optics.
We are smarter now because publishers have acquired all these new tools and have forced us to meet these new standards.
\"There are a lot of color challenges related to matching colors.
For example, the product can be produced in more than one location, and the item may have different colors if there is no color agreement.
\"The company is doing more and more printing on multiple sitesto and can ship wherever it is needed, you may have two boxes side by side on the shelf and print on two different websitesDownes said.
\"If they look different, consumers will come to the conclusion that the quality is inconsistent.
If you print in two factories, the two instruments must have a high consistency.
\"Even if one color looks the same in regular light, it may be different under another light source.
\"A potential problem is called color permanence, when the apparent color of the printed material changes significantly due to the type of light source that illuminates the item,\" said Mr. Good.
\"The other is called the same color spectrum, when a product printed with a different ink formula matches under one illumination (
Such as fluorescence used in retail stores)
, But does not match under another light source (
Such as tungsten wire used at home).
The splitter measures the color of the product under different lighting conditions and can be used to test these problems.
\"When a customer prints out a digital proof, they look for samples that are not readily available to match.
KenFerguson said: \"Customers are looking for colors that appear on their computer screens in order to appear on the media, but when it appears on the media, it usually doesn\'t look exactly the same, technical Director of Van Sen Dutch ink.
\"You can make adjustments to a certain extent.
The customer may give you an original match on the carton and they will want to see this color on all the different substrates.
It becomes an art form and you can put it somewhere.
\"New products, new and improved measuring tools make the ability to judge colors, communicate, and store results more effective.
\"The color measurement tool has made great progress,\" he said . \"Ferguson.
\"A device as big as a large microwave oven is now Manual. held.
The software itself is much better and you can use different substrates and lighting devices to create an accurate database for the recipe.
\"Hunter Labs specializes in quality control solutions and provides QC software as well as hand-held and desktop color measurement metering . \"Good said.
Its products include its MiniScan XE Plus, a portable spectrum-
Measuring instruments based on color.
Hunter Lab also provides color formulation software for opaque coatings.

\"Its purpose is to check the color of the purchase,\" he said . \"Fusco.
\"It enables users to compare different color systems such as CIELAB, CIELCH, and Hunter Lab.
It also brings different colors.
If the customer is happy with the color, they can scan the itin and it will give the lab number to be recorded in memory as a standard.
It will then be in a later sample and give you deltadifferences.
Parameters and databases can be set.
\"Color Consistency crashes once the media is running.
Colorurvalid Co. , Ltd. has developed a color effective color monitoring system that can measure colors at higher temperaturesFast internet news.
\"Unless you stop running, you can\'t tell if the run is correct. You have a system that monitors colors in real time at full speed . \"Roworth said.
\"It will monitor 50 or more color check areas every 10 seconds.
It enables the printer to prove that the color is accurate because it prints out precise information about whether it deviates from the specified tolerance and where it occurs.
\"As the cardboard PDQ industry enters the new century, consumers will certainly seek more consistency and quality.
By improving the measurement technology, printing ink manufacturers will be able to meet these requirements.
