High CRI, 5000K FluorescentSuperior Color AccuracyThe GTI Graphiclite spectrum in Figure 4 (at bottom) delivers coloraccuracy that is superior to any other lamp on the market.Spectral IrradianceSpectral IrradianceDue to GTI’s commitment to the ISO standard and guaranteedquality, our Graphiclite 100 color viewing lamps have developeda reputation for unparalleled excellence. This is mainly a result oftheir close match to the D50 spectral specifications and thus theirtight compliance with ISO 3664 standards.D50StandardCurveUnlike high CRI 5000K lamps with irregularspectral output curves, the Graphiclite 100 lampspectral curve is even and smooth and deliversthe closest fit to the CIE D50 curve. This tight fit,along with lamp output consistency and rangeof lamp sizes, is one of the key reasons why GTIviewing products lead the world for critical colorimage viewing. Quality and performance isfurther guaranteed by tight manufacturingtolerances in lamp production.The spectral power distribution of Graphiclite 100lamps is the key to their superior rendition ofcolor. While it is important to meet all of theISO 3664 parameters to receive the full benefitsof the viewing standard, the most importantfactor is the spectrum of the light falling on the colored image.The spectral power distributions in Figures 1–3 (below) illustratehow three different lamps, two fluorescent and one LED, attempt torecreate the CIE D50 spectrum. It is clear that each of these lampswould render color differently from each other as well as from therendition specified by ISO 3664. LED technology is improving at arapid pace. However, at present, it does not deliver a good enoughspectral match to the D50 target to have application in GTIGraphiclite viewing systems.World Leading Critical Color Image Viewing400.6.4GTI’s color laboratory assures the accuracy and consistency ofGraphiclite 100 color viewing lamps and all Graphiclite productsbefore they are released for shipment. At GTI, we stand behind ourproducts and services while continuing to meet the ever changingneeds of our customers. We make no compromises.350.5.5The international standard is ISO 3664:2009entitled “Graphic technology and photography–Viewing conditions.” The standard specifies lightquality, intensity, illuminating-viewing geometry,surround conditions, and evenness. All GTIGraphiclite color viewing systems conform tothe ISO 3664:2009 standard.300.4.6Spectral IrradianceProducing and printing high quality color is acomplicated process that demands accuracyand consistency. Far too often, incorrect andinconsistent lighting and viewing conditionsresult in costly communication problems duringthe color reproduction process. To combatthese problems, the industry has establisheda set of technical specifications defining tighttolerance D50 viewing conditions.Figure 2. Low CRI, 5000K 0Wave Length (nm)Figure 3.

DIGITAL COLOR MANAGEMENTSoft ProofingSoft proofing systems enhance the digital color managementworkflow by allowing an optimal intensity match between hardcopy artwork and a color monitor. GTI’s soft proofing solutions willhelp you to shorten the production cycle and reduce cost, whileimproving customer satisfaction.At left: Soft View SOFV-1xiQwith iQ sensor. The systemmatches the lighting in theviewing station to theluminosity of a monitor.Desktop:Soft View SOFV-1xiQThe SOFV-1xiQ is an ISO 3664:2009 D50 compliant desktop softproofing system. The 1xiQ includes a viewing station with a19.5" 24" (50 cm 61cm) viewing area and GTI’s unique iQwireless light sensor. The viewing station includes adjustable lightshields for upper and lower luminaires to enhance light uniformity,removable side walls for viewing of larger pieces, digital dimmingcontrol, and easy access front panel user controls. The iQ sensormeasures the brightness level of a monitor. This data is transmittedto the viewing station and used to set the light level of the Soft Viewto achieve an optimal match to the luminosity of the monitor.The iQ sensor is also used to measure ambient light level and tocalibrate the viewer. The SOFV-1xiQ provides accurate calibrationand luminance —no wires, computers, or software are required.Pressroom:MCVE/iQ Modular Color Viewing EnvironmentIdeal for web press consoles, the MCVE/iQ is a custom fit viewingsystem for soft proofing.It adapts to your pressconsole and provides fulland variable intensitylighting plus a slidingsingle or dual LCD mountthat rotates out of the wayof the signature panel.Right: MCVE/ iQ system onpress consoleSoft View SOFV-1xiThe SOFV-1xi is also a D50 viewing system, with a 19.5" 24"(50 cm 61cm) viewing area, for soft proofing.

The lampsare manufactured with a unique blend of fluorescentphosphors and produce a true full spectrum whitelight which renders colors with the highest degree ofaccuracy and efficiency. In a GTI viewing station, a Graphiclite lamp produces acolor rendering index (CRI ) approaching 95.Viewing systems include a reflector, diffuser, the booth structure, geometry ofillumination, and Graphiclite 100 lamps. A change in this system’s formulationcan create a slight color cast that will impact color assessment resulting in aviewing environment that is not ISO compliant. To maintain an ISO 3664:2009compliant viewing system, use only Graphiclite 100 lamps and relamp regularly.The graphs at right depict the spectral power distribution of two fluorescent5000K lamps compared with D50. The one on the top, Graphiclite 100, deliversa much closer match to the D50 curve and, therefore, delivers much greatercolor fidelity and tighter compliance to the ISO 3664:2009 viewing standard.Graphiclite 100 D50 LampD50 Standard CurveSpectral Power DistributionCommercially Available D50 LampD50 Standard CurveWhen to RelampA fluorescent lamp’s color output and intensity changes over time. To maintainconsistent and accurate viewing conditions, viewing stations should berelamped after every 2,500 hours of use.GTI Graphiclite viewing stations should be relamped only with Graphiclite 100color viewing lamps. Relamp kits are available for all Graphiclite viewingproducts. Visit www.gtilite.com for details.LiteGuardLiteGuard II tells when the viewing system is ready to use, the lamp hoursused, the lamp hours remaining before replacement, and when relamping isrequired. LiteGuard II is standard with many GTI viewing products and isavailable as an option on many others.Graphiclite 100 lamps (top) provide a much closermatch to the D50 curve, resulting in greater color fidelityand tighter compliance to industry standards.
