Creo SQUAREspot thermal imaging predictability and consistencyassures plate imaging integrity. Advanced automation, customized, inlinepunch assures accurate and repeatable notches for perfect register on press.Driven by a Brisque, the Lotem 800 II Quantum is for the discriminatingprinter who cannot compromise. This ultimate computer-to-plate (CTP)device meets and adapts to all your needs for efficient, continuousproduction that keeps the presses running.Creo is a pioneer of thermal imaging, the de facto standard CTPtechnology today due to its outstanding performance and quality.SQUAREspot thermal imaging maintains consistent reliable plate imagingdespite normal process variation such as changes in plate sensitivity orprocessor chemistry. This precise process control enables reliable FMscreening and artifact-free images.The fully automated platesetting sequence produces press-ready plateswithout your intervention. Plates are loaded automatically from a cassette,after automatic slip-sheet removal. The customized, inline punch systempunches plates according to the press profile selected on the workstation.Then plates are automatically mounted on the drum for imaging andunloaded directly into an optional inline processor.The Lotem 800 II Quantum includes:Lotem 800 II Quantum Plate size ranges from 457 x 381 mm (18 x 15 inch)to 1130 x 905 mm (44.5 x 35.4 inch).Lotem 850 Quantum Plate size ranges from 457 x 381 mm (18 x 15 inch)to 1160 x 950 mm (45.67 x 37.4 inch).Available in the following configurations:• Single cassette• Dual loading cassette (See DLC for Lotem 800 User Guide,399Z1R080B)• Multi cassette unit (See MCU for Lotem 800 User Guide,399Z1R092)

Lotem 800 II Overview 3Lotem 800 II OverviewThe new Lotem 800 II platesetter offers higher throughput, more speedoptions, and optional thermal halftone proofing.More speed options mean that printers can match throughput to theirproduction needs. The Lotem 800 II platesetter offers new speed optionsthat improve throughput up to 25 plates per hour. Adding the optionalthermal halftone proofing produces proofs from the same digital files,using the same screening and same halftone dot structure used to imagethe plates. The resulting proof is exactly what will be printed.Lotem 800 II is fully automatic, with additional speed and throughput,support for thermal halftone proofing.Available models:Lotem 800 II Speed - (S speed) 10 pphLotem 800 II Speed - (F speed) 16 pphLotem 800 II Speed - (V speed) 25 pphAll in two resolutions 2400/2540 dpiSpectrum option is available for all modelsFor more details on the Spectrum option see the Lotem 800 II Family withSpectrum User Guide, 399Z3R873A.The Lotem 800 II uses a thermal imaging head 830 nm just like any otherCreo CTP device.The Lotem 800 II does not support thermal compensation.Lotem 800 II plate size ranges from 457 x 381 mm (18 x 15 inch) to 1130 x905 mm (44.5 x 35.4 inch).

Using the Single Cassette 29Using the Single CassetteReleasing CassetteLoading plates into the single cassette requires:• Releasing cassette from platesetter• Loading plates into cassette• Inserting cassette into platesetterYou need to release the cassette in the following cases:• To add identical plates to the cassette currently in the platesetter• To load different plates in the cassette currently in the platesetter• To insert a new cassetteNote: The cassette pins remain depressed whenever a cassette is not loaded,providing that both upper doors are closed and the loading system has not beenmoved.1. Click Cassette Setup on the Main Operations menu. Then from themenu that opens, select Release Cassette, or:click on the cassette on the Online machine view. The Online machineview will then show the cassette outside the machine.Figure 11: Main window showing the released cassette

30 Chapter 3 – Plate Handling2. The pins that lock the cassette inside the platesetter are released. Youwill hear a tone indicating that the cassette lock is released.3. Go to the front of the cassette, and with your foot release the stoppersthat lock the wheels of the cassette.4. Pull out the cassette.5. Roll the cassette to the location of the plates.Loading Plates in Single CassetteTo load plates in the cassette (see figure on page 32):Note: The cassette should be near the location of the plates (the plates are heavyand you want to avoid carrying them).1. Open the two side latches of the cassette to open the cassette cover.2. Release the three plate guides (left, right and back guide), by openingthe knob of each guide.3. If the plates to be loaded are not the same size as the plates previouslyloaded, do the following:push the side guides outwards toward the cassette sides. Note thatwhen you move one side guide, the other side guide moves as well.Push the back guide toward the back edge of the cassette.Note: If the new plates are the same size as the plates previously loaded, youneed to move only the side plate guides to avoid scratching the plates.4. To prevent scratches on the bottom plate, the bottom plate should beplaced on a piece of cardboard and not directly in the cassette. If yourplates are not packaged with a bottom protective cardboard, place asuitable piece of cardboard (same size as plates) in the cassette.5. Place the plates, emulsion side down, inside the cassette on thebottom cardboard.Note: You should wear protective gloves to protect your hands from the sharpplate edges and to avoid leaving fingerprints on the plates.

Using the Single Cassette 316. If you are loading several packages of plates, make sure there is nocardboard between the different packages (cardboard is required onlyunder the bottom plate in the cassette).7. Move the left or right plate guide toward the plates, until the roundedtip of the side guide touches the plate edge (this prevents the sideguides from forcefully pressing against the plate). The guidesautomatically center the plates in the cassette (to ensure that whenloaded onto the drum, the plate is aligned with drum center).Note: If more than 25 plates are loaded, you need to use your hands to movethe plates and align them with the plate guides.8. Move the back plate guide toward the plate edge. Make sure the guideonly slightly touches the plate edge.9. Close and tighten the knobs of the three plate guides.10. Close the cassette cover and lock the two latches.

Instead, the CurrentCassette window will automatically open, as shown on the previous page.Note: You can always open the Cassette Configuration window from theSettings menu.Defining Offline CassetteOffline Cassette enables you to define the plates of the cassette that iscurrently not in use, and is available for all cassette configurations. TheLotem 800 II is supplied with one cassette, but you can purchase additionalcassettes.Note: For single cassette, this procedure is relevant only if you have more thanone cassette.Defining plates before the cassette or tray are actually inserted into themachine saves operation time. While the machine is processing plates fromone source (such as, another cassette), you can define the plates in anothersource. Later, when the second source is inserted, the Current Cassettewindow will open with the correct plate name and quantity.

Defining Offline Cassette 37To define offline cassette:1. From the Routine Functions menu, select Offline cassette. The OfflineCassette window opens.Figure 17: Offline Cassette window (for DLC main)2. From the Cassette Name select the cassette name. If you changed thedefault cassette name, the new names will appear in the List Box.Otherwise, the default names will appear (001_Main in the windowapplies to the main compartment of the DLC).Note: To change the default cassette names, use Cassette Configurationunder the Preferences menu. See page 34.

38 Chapter 3 – Plate Handling3. From the Name box, select your plate name. Available names are theplates defined in the Media Definition window. The plate parameterswill then appear for the selected plates.4. In the Quantity box, type the number of plates in the cassette.5. Click Apply to confirm the window setting.When this single cassette is inserted into the machine, the Current Cassettewindow will automatically open with the above setting.Plate GeometryThis section describes aspects of the plate geometry and image area. Theseaspects will help you plan for the plate exposure process and define thecorrect settings for your press and plate, and for your image offset.Head margin – defined on the Brisque, as one of the Press formatparameters. It defines the distance from the plate edge until the beginningof the layout or the exposed image. This parameter is also known asleading edge to print.

Plate Geometry 39Tail margin – defined on the Brisque as one of the Press format parameters.It defines the distance from the back edge of the plate to the edge of the fileor layout.H (height) – plate height (around the drum).W (width) – plate width (along the drum width).In a negative exposure of a positive working plate, there is always anemulsion area on the plate that is not exposed, therefore emulsion areasremain. The size of these areas is determined as follows:• At the head, the area is equal to the width of the plate and at a height ofup to 6 mm.• At the tail, the area is equal to the width of the plate and at a height ofup to 6 mm.The image alignment is determined by the Alignment, as defined in thePlate Expose window on the Brisque or in the Output Process Plan in thePrinergy. For details, see Brisque to Lotem 800 II / Lotem Quantum FamilyConnectivity User Guide, 399Z1R762 or Prinergy to Lotem 800 II / LotemQuantum Family Connectivity User Guide, 399Z1R512B.
