This reminds me of a customer (large retail catalogue & stores) who specified Deluxe Cool White for critical color viewing/matching. Their plan was that when the customer brought the goods to the customer service area in the store, they would compare the catalogue to the item under that same...

We are considering installing water sprayers in our color viewing stations to simulate rain while viewing the color print quality … would save the walk outside the building! --- just kidding!

Thank you for this recollection .. feels like yesterday but also feels like so long ago. I was exhibiting at Print 01 as well and had the good fortune to bum a ride to Newburgh, NY from the CreoScitex folks heading back to Boston - about a 24 hour ride as well. We lost some local community...

Metamerism is a little like Murphy's law ... it often occurs when you least want it. The Graphic Arts & Photographic industries decided many decades ago (mid 60's as British Standard BS-950 or early 70's as ANSI PH-2030) that the materials used in printing and photographic reproduction were...

Nice one Gordon. I really like the Yikes.

Hi there, We (GTI) manufacture a range of compact desktop color viewing booths called PDV (Professional Desktop Viewers). These models range from 11" x 16" up to 23" x 25" in size and $470 - $900 in price (side walls are an additional option). Here is a link to our website which includes a...

Yes you can however it would require us to design a custom bracket to attach the GLL-440 to the wall bracket - which would take time and add cost. You are welcome to contact me by email to discuss this further ( [email protected] ) Bob

Installation of GLL 440 for Wall Illumination Installation of GLL 440 for Wall Illumination Dear Indy - You can use the same installation geometry for the GLL-440 as the GLE-1032P described in the previous instructions. The prismatic lens of the GLL-440 will diffuse the light over the wall...

Yes. D50 is a CIE defined spectral power distribution - which is the key driver for how a color appears to the observer (besides reflectance and absorption characteristics of the color itself and the color response of the person doing the viewing). Very small differences in the reflectance...

Making a pair of metamers that behave close to perfectly is very difficult. It boils down to very slight formulation tweaks that are based on the color vision of the person creating the two colors (we have a metameric pair produced for us and it is quite common for 2 or more people to see the...

Is the swatch something other than ink on paper? Is the swatch something other than ink on paper? The responses above are quite correct that there is a lighting environment specified by the graphic arts industry (ISO 3664:2009) that spells out the conditions under which critical visual color...

installing GTI GLL overhead luminaire installing GTI GLL overhead luminaire Dear Indy, The installation does depend on the size and orientation of your viewing surface. I have attached installation instructions for our GLL luminaires for your review. I have also included a flier which...

How a lighting company got into the paint business How a lighting company got into the paint business As Henry Ford is quoted as saying ..."Any customer can have a car painted any color that he wants so long as it is black." GTI is in a similar position in that we sell only neutral gray paint...

most likely lamps for console most likely lamps for console Since the press is from Germany, the 36 watts would indicate a 4' T8 (1" diameter) lamp. You will get good results with our F32T8/GL50 lamps. These are 32 watt lamps that fit into the 36 watt circuit and provide a very good spectral...

The right lighting for press consoles The right lighting for press consoles Good question. The recommendation is that all critical color viewing locations (press room, pre-press, client viewing, etc.) comply with ISO 3664:2009 - the international standard that specifies the conditions...

Change in ISO 3664 suggests no UV cut measurements Change in ISO 3664 suggests no UV cut measurements Based on the recent change to the ISO 3664 standard for color viewing (2000 --> 2009) I believe that you will want to include UV in your measurements. The new ISO standard (3664:2009) carries...

Variable light intensity is great for soft-proofing Variable light intensity is great for soft-proofing If Repairguy is implementing soft-proofing in his press room then a variable intensity viewer would be almost a necessity. If he is simply setting up a lighting environment, or simply...

That's very true, Gordo. Consistent appearance of the colored image through out the production process is the greatest benefit that the ISO standard can deliver. The other key benefit - an environment that is optimized to allow the press operator to detect color differences between an approved...

The Problem with Metameric Strips as Compliance Indicators The Problem with Metameric Strips as Compliance Indicators The use of metameric strips (like the ones from GATF) to verify that a viewing system is still 5000K or in compliance with ISO 3664 specifications is not recommended for the...
