DTP34 DENSITOMETER Overview and Setup Instrument Description X-RiteColor® DTP34 QuickCal Densitometer is a color measurement instrument that reports densitometric and dot data. The instrument is designed to calibrate color output devices including large format printers, proofers, and digitally connected color copiers. X-RiteColor® DTP34 QuickCal Densitometer is a “drop-in” replacement for the X-Rite DTP32 instrument.
DTP34 DENSITOMETER Instrument Interface The Quick Cal Densitometer must be interfaced directly with one of the computer’s Serial Ports. Installation differs slightly for Macs and PCs (see below). For attachment to a Mac Mini-DIN 8 Serial Port, you need to use the optional adapter (P/N SE108-DB9PA-01). NOTE: Quit all programs and shut down the computer before installing interface cabling.
DTP34 DENSITOMETER Instrument LED Indicator The LED indicates a variety of instrument operation conditions, such as calibration mode, and operation. Below is a complete list of all conditions reported by the LED. Operation Mode • Solid Green—self-test passed and instrument is ready for use with defined strip. • Slow Flashing Green—strip reading in progress or waiting to read a strip. • Fast Flashing Green—strip reading was attempted but the wrong strip was read, or strip was skewed during reading.
DTP34 DENSITOMETER Calibration The X-RiteColor Quick Cal Densitometer has a unique semi automatic calibration feature. When the reflection reference is scanned, the calibration values are also automatically scanned. Frequency of Calibration Your QuickCal Densitometer should have a Quick Calibration performed weekly. A Full Calibration should be performed annually, during heavy usage to provide accurate measurements, or if the Quick Calibration consistently fails.
DTP34 DENSITOMETER Measurements Measurement Notes and Tips • You should refer to the documentation for the software program that you are using with your instrument. All applications that utilize this instrument must be running during measurements. • The strip must have at least a 1.2″ (30.5mm) leader before the leading edge of the first step. Contact X-Rite Applications Support if additional information is required. Inspect the strip for spots or defects on the steps.
DTP34 DENSITOMETER • The darkest patch of a strip must be read first unless there is at least 1.1″ (27.9mm) unprinted trailer after the last patch. • When possible, strips should be read so that the instrument does not ride on un-read patches. This prevents accidental marring of un-read patches that may cause reading variations. • To obtain consistent measurements the same backer should be used underneath every sample. ANSI/ISO specifies a neutral gray of at least 1.5D, which will appear black.
DTP34 DENSITOMETER Spot Measurement Your QuickCal Densitometer is designed to read spots, single readings of specific locations. This feature can be manually activated or if supported, activated by your software application. Refer to your software program documentation to see if this feature is supported. To manually activate this feature, scan the “Spot Read” X-Rite Setup Barcode enclosed. 1. 2. 3. 4. Select a desired target of at least .5″ (12.7mm) diameter.

DTP34 DENSITOMETER General Maintenance Cleaning the Instrument Your instrument requires very little maintenance to achieve years of reliable operation. However, to protect your investment and maintain reading accuracy, a few simple-cleaning procedures should be performed from time to time. General Cleaning • Whenever required, the exterior of the instrument may be wiped clean with a cloth dampened in water or mild cleaner.
DTP34 DENSITOMETER • If required, a new calibration reference can be ordered from X-Rite. Order calibration reference part number DTP34-100-KIT. Always handle calibration reference by the edges.

DTP34 DENSITOMETER Appendix A - Operational considerations between a DTP32R and a DTP34 The DTP 34 Quick Cal Densitometer is a “drop in replacement” for the X-Rite DTP32R (R for reflective) strip reading densitometer. Display There are a few differences in operation of the Quick Cal compared to the DTP32. The Keyboard DTP32 (see diagram at right) has a display, keyboard, and strip guide, whereas the Quick Cal product has a single key and the different process of reading a strip.
DTP34 DENSITOMETER Appendix B - Barcode Operation You can change several configuration settings of your QuickCal Densitometer using the special format barcodes supplied by X-Rite, Inc. or your software provider. These set-up barcodes consist of multiple strips that must be read in the proper order. In most cases your software will automatically configure your instrument.
