Driver configuration Ink configuration and driver version According to your ink configuration, please use the matching driver. We implemented only the most relevant cases of ink configuration.

At the time this tech note is written, the RJ-45 port is only here for maintenance. Procedure 1. Please go to Server Admin and configure your driver in USB. 2. When connecting the printer for the first time, its name is attributed to the connection. 3. You may have to stop the server in Server Admin, then restart the interface of the printer in Caldera to have it configured properly. Be careful: it may be advisable to disable Rip-While-Rip in Misc. tab (Server Admin). Also, on some Macintosh (MacMini), you may have to change the USB port, where you plug the printer if you encounter connection issues during print. 1 Caldera 2016 MIMAKI UJF-3042FX, UJF-3042HG & UJF-6042 Resolutions and qualities Resolutions with 300 dpi in one direction are not implemented, since practically they don't give enough ink density. There is no bidirectional printing (hardware limitation). Printer and media parameters Printer parameters Refresh level: frequency of head quick cleanings during print Scan width: width of the carriage movement, either full size of the table or width of the job Action: select if you want to print and irradiate with UV at the same time, only irradiate or only print without irradiation Mode at end of job: put the printer in Remote or Local when a job is finished Advanced parameters: connection parameters Media parameters Feed adjust: correction of the height-axis movement Overprint: put more ink UV lamp number (for UJF-3042): early UJF-3042 only have 4 lamps, whereas updated versions have 8. If 4 is selected for one printer with 8 lamps, lamps are grouped by two (UV lamp 1 parameter sets lamps 1 and 2…) UV lamp X irradiation level: strength of the lamp Variable dot selection: ink quantities associated with the 3 levels of data in Variable Drop resolutions (resolutions without -Fix suffix). Since this printer actually uses multidrop (several 7 pl droplets at the same position or pixel) to achieve these levels, a set with more ink will be slower Fixed dot selection: ink quantity for one position (pixel) for Normal Drop resolutions (-Fix suffix) Vardot level: in Variable Drop resolutions (multidrop), change the amount of 1-drop and 2-drop pixels relatively to 3-drop pixels. We advise using a value between 50 % and 70 %. Default value is around 70 %. If on linearizations you encounter density drop or discontinuities at middle densities, you can lower this value to fix the issue Special inks and special effects Special effects are achieved by layering different jobs configured to use primer, white, color or varnish (Clear Coat). Contrary to some other Caldera drivers (SureColor-S70600, Mimaki-JF/JFX, Roland LEC), each layer must be sent in a different job. We strongly advise to save each layer configuration in a print configuration (above the 5 icons in the 1st window of the printer). This way, you won't have to enable-disable everything every time. How to configure special inks Procedure 1. Ink selection can be done by selecting a color mode in the 1st window of the printer: Mode CMYK White + CMYK CMYK + White Primer + CMYK CMYK + Clear Coat White only Primer only Clear Coat only Use Colors only White under colors in one pass White over colors in one pass Primer under colors in one pass Clear Coat over colors in one pass White only (1 or 2 channels) Primer only Varnish only 2. You must enable corresponding tab(s) in Page Setup window. Other special ink tabs must be disabled. 3. In the tab, configure the method and source you want to use for your special ink (Full page coverage, Generate from CMYK data…) to achieve selective printing for this layer. At the bottom of the tab, you can define a linearization curve. Be careful, density set in Full page coverage is relative to your linearization: if the linearization is set to 50% for a 100% input and you set a 50% density for Full page coverage, you will actually get a 25% absolute density! 2 Caldera 2016 MIMAKI UJF-3042FX, UJF-3042HG & UJF-6042 4. Save this in a printer configuration (1st window, above the 5 big icons). 5. For UV-only passes (no printing, just scanning with UV ON), you must change the printer parameter Action (wrench icon, Printer tab) from Print and UV to UV only. Remark: if you want to achieve matte and glossy varnish finishing, you MUST have two different media with their parameters (UV lamps) configured for one case and the other: since both finishings use the same resolution and mode (Clear Coat only), they share the same media parameters if you don't set two media. How to achieve a good rendering using all ink (primer, colors, glossy finish). This has been tested with LH-100, CL-100 and PR-100 inksets. Since all layers are defined in a different job, you can switch resolutions to the optimal parameters for each layer. Primer Resolution: 720x900 (Variable Drop, not the -Fix) Mode: Primer only Quality: 24 pass Maximal density must be 30% (30% in full coverage) UV lamps (Media parameters): 120% A PRIMER LAYER IS ADVISED ON GLOSSY MEDIA AND METAL Colors You can use whichever quality suits your needs in term of quality and speed, but Mimaki advises to use the following modes: 720x600, 16 pass 720x900, 24 pass 720x1200, 32 pass 1440x1200, 16 pass 1440x1200, 32 pass 1800x1800, 24 pass 720x600-Fix (Normal Drop), 8 pass Varnish To ensure a good grip for the varnish in glossy mode, it is advised to print a layer of matte varnish wherever you want to put a glossy finish. Then, to achieve the glossy finish, you must print it with few or no irradiation to let it flatten, then fix it with few irradiation to avoid wrinkles, then harden it with more irradiation. Case A: using 720x600 1st layer: matte varnish at 8 or 16 pass, UV at 100% 2nd layer: glossy varnish at 4 or 8 pass with a lot of ink (>= 70%), UV lamps at 0 or 10% max 3rd layer: UV irradiation to fix at 8 pass, UV lamps at 20-30% max to avoid wrinkles 4th layer: UV irradiation to harden at 8 pass, UV irradiation at 100% Case B: using 720x900 Same as above, but pass numbers change 1st layer at 12 or 24 pass 2nd layer at 6 or 12 pass 3rd and 4th layers at 12 pass 3 Caldera 2016
