Section Two Contents Instrument Applications Instrument Operation Strip Guide Strip Measurement Instrument Calibration Strip Setting (Editing) "np" Factor Calculation Data Output Selection (Parsing) Measuring Leaderless Strips INSTRUMENT APPLICATION S E C T I O N T W O 2 Operation X-Rite DTP densitometers can be used in many different instances and varying circumstances, three of the most likely applications are given below. The most common application is where an X-Rite DTP densitometer is interfaced with a computer and software package. These three items makeup a color management system. The X-Rite DTP densitometer provides data for the color management system, enabling the software to calibrate color output devices such as ink jet, thermal transfer and dye sublimation color printers. The software package configures the densitometer, allowing instrument configuration and editing procedures to be omitted. A second application is where an X-Rite DTP densitometer is interfaced to a computer. The computer lacks software, which supports instrument configuration. In this circumstance data can be sent to spreadsheet and database application software for compiling and viewing. A minimal amount of configuration must be completed using the instrument. See Section 3 for Instrument Configuration. A third application is using the X-Rite DTP densitometer as a stand-alone unit, not interfaced with a computer. Data can be viewed using the instrument keyboard and display. The AC adapter would be used to power the instrument. The instrument must be configured using the instrument keyboard. See Section 3 for Instrument Configuration.Paper Strip When a particular paper strip is selected, one or both of the displayed paper guide setting numbers flash. If only one guide setting number is flashing, this indicates the guide that the strip rests on first when measuring. In most cases this only occurs on a strip that required multiple passes such as, Fuji CP-21. Both guide setting numbers flash on single pass strips. 2-1
S E C T I O N T W O INSTRUMENT OPERATION STRIP GUIDE The X-Rite DTP densitometer is simple and easy to use. The steps for instrument operation vary only slightly, depending on the type of application it is used with. Step 1. Unpack and Inspect. (Section 1.1) Step 2. Apply Power. (Section 1.2) Step 3. Interface Instrument (Section 1.3) and/or Configure Instrument. (Section 3) Step 4. Position Strip Guide. (Section 2.3) Step 5. Measure Strip. (Section 2.4) The densitometer has an adjustable strip guide on the front of the instrument. This strip guide moves left and right to accommodate different size strips. After selecting a strip (2.4 Strip Measurement, Step 2) the strip guide pointer must be moved to the corresponding stop location number appearing in the instrument display. (See Section 2.6 Strip Setup (Editing) for information on Stop Location Number.) The strip guide can be positioned from 1/2" (12.7 mm) to 3" (76.2 mm) to the right of the center triangle, in 1/2" (12.7 mm) increments. Display Center Diamond Strip Guide 10. 20. 30. Move the strip guide by sliding it left or right. 2-2
O P E R A T I O N STRIP MEASUREMENT An instrument NOT interfaced to a computer with color management software must be configured before a strip can be measured (See Section 3, Instrument Configuration.) 10 20 30 Guide Strip (with slight pressure) on edge while it is being pulled through the instrument 2-3
S E C T I O N T W O Measurement Notes - Feed the strips into the instrument so the darkest steps are read first. When "auto" or "cont" is selected the first step s density must be 0.5D greater than the Dmin (substrate), this insures proper pattern strip recognition. - A 1.25" (30.5 mm) leader should precede the leading edge of the first step. If this is not possible, refer to Section 2.9 for information on measuring leaderless strips. - Inspect the strip for spots or defects on the step. Defects may cause inaccurate measurements. - Position strip against the strip guide. Insert strip until it stops against the drive roller, [approximately 3" (76.2 mm)]. One or two seconds after contacting the roller, the motor activates and automatically pulls the strip through the instrument. Guide the strip with slight pressure, continually pushing the strip against the strip guide. This prevents skewing of the strip as it is being measured. Measurement Procedure NOTE: Illustrations depicting menu views represent the DTP36 model. Menu views for the DTP32 and DTP32TR differ slightly. The DTP32R only displays reflection functions. The DTP36 film measurement procedure is similar to the paper measurement procedure. 1. At Main Menu level, continually press [p#] until "p1" appears, then press [pap] for paper strip, [film] for film. Pass Name 2. Select desired strip setting. Press [other] and page through available selections. Stop paging when desired strip appears. Guide Location 3. Set strip guide to the location appearing in the instrument display. 4. Align strip with the strip guide, darkest steps entering the instrument first. 2-4
O P E R A T I O N NOTE: If uncertain which end to insert, follow software or hardware manufacturer s instructions. 5. Insert strip into instrument until it rests against drive rollers, [approximately 3"(76.20 mm)]. Keep right side of strip against strip guide. A one second delay occurs before drive rollers activate and automatically feed strip through the instrument. NOTE: If the strip gets jammed, press the two keys labeled "MENU." If strip still does not feed through instrument, slowly pull strip out front of instrument. Check strip condition, creased strips cannot be measured. 6. "PASS #1 OF 1 OK" appears in instrument display if measurement was successful. NOTE: If "INVALID READING", "BUFFER OVERFLOW", or "UNRECOGNIZABLE STRIP" appears after strip is measured, reread strip. If the same error message occurs after re-reading strip, refer to the Appendix B. When the strip has more than one pass to measure, the instrument displays the next pass to be measured. Repeat steps 3 through 5 until all passes have been completed. 7. Transmit data. Auto Transmit On "TRANSMITTING DATA" appears after each pass or at the end of all passes, depending on the setting of the "DAP" option in configuration. After data transmission is complete, the instrument display returns to the screen selected in Step 2. 2-5
S E C T I O N T W O Auto Transmit Off NOTE: Each step's data can be viewed by pressing the [$] or [@] keys. To display a different pass, press the far right key [ie. (cyn)]. The measurement data appears in the instrument display. Press [xmit] to manually transmit the measurement data. 8. Press the two keys beneath [MENU] to return to the "Main Menu" screen. 2-6
O P E R A T I O N INSTRUMENT CALIBRATION The DTP densitometer has a unique feature called Auto-Cal. When the instrument performs a calibration procedure, the cal strip is measured; its cal values are automatically scanned, simplifying the calibration procedure. The instrument employs a number of self-checking procedures to verify calibration accuracy during normal use. When internal limits are exceeded, a calibration message appears in the instrument display. Calibration is recommended at this time. Calibration should be performed approximately once a week or when indicated by the instrument. NOTE: The Auto-Cal strip can be cleaned with a mild soap detergent. DO NOT clean below the bottom triangle. The attached label is not coated and will smear when moisture is applied. DO NOT get fingerprints on any portion of the strip, handle by the edge. To replace a worn or damaged Auto-Cal strip contact X-Rite or your local dealer. Order Part Number DTP32-100. 2-7
S E C T I O N T W O Density Calibration Procedure 1. At Main Menu level, repeatedly press the [p#] key until "p2" is displayed. Press [cal] to activate calibration. NOTE: The DTP32R is a reflection instrument only and will bypass the "den/tdot" and "Calibrating Transmission" screens. 2. Press [den] key. "CALIBRATING TRANSMISSION" is displayed as the unit automatically calibrates transmission (reads air). "INSERT CAL STRIP" appears. 2-8
O P E R A T I O N 3. Insert the Auto-Cal strip into the 35 mm slot until it stops against the drive rollers. The strip indicates which end to insert. 4. "Reading momentarily appears in the display. The calibration density values and "CALIBRATION OK momentarily appear. The density values displayed can be found on the Auto-Cal strip. NOTE: The DTP will automatically return to the Main Menu. If "UNRE- COGNIZABLE STRIP" appears in the instrument display, smudge marks may be causing an error message. Try cleaning strip, see page 2-6. 2-9
S E C T I O N T W O Transmission Dot Calibration (DTP32, DTP32TR, & DTP36 Only) When calibrating dot it is important that a cal wedge with a true 50% dot area (e.g.; UGRA Plate Control Wedge, GRA Dot Ref, etc.) is used. Transmission Dot Calibration Procedure 1. At Main Menu level, repeatedly press the [p#] key until "p2" is displayed. Press [cal] to activate calibration. 2. Press [Tdot] key. 3. Insert the base film into the strip slot. Use the alignment mark on the front of the unit to center the filmstrip.
