PART II - ABOUT HANRUN SUBLIMATION PAPER
Q:What is a RIP software?
A: A Raster Image Processor (RIP) is software that contains all the necessary modules to "translate" (rasterize) print files for output systems, such as large format printers (LFP). It includes modules for data management, ICC profiling, color and output control which can be summarized within the so called print environment.
Q:What is the print environment?
The print environment is a full set of printer settings, which allows the operator to print out all files in the same way. It includes e.g. the settings speed, resolution of the printer and number of passes. Furthermore the calibration like linearization and ink limitations (per color channel and in total). Finally also the ICC color profile.
Q:What is an ICC color profile?
The ICC color profile displays a 3D-color space (L*a*b*) of a particular set of printer, ink and media combination which is implemented into the print environment.
Q:How can i create my own print environment including icc color profiles?
Necessary is a color measurement device (spectrophotometer) and software for profile creation. The main steps to create a print environment are:
·Linearization (The way printer controls the amount of ink)
·Setting a total ink limitation
Q:Which temperatures and transfertimes are recommended?
For dye sublimation transfer with Hanrun® higher calendering temperatures are beneficial. For best results we recommend to use a transfer temperature of 205°C to 210 °C. Using this temperature will enhance the transfer quality e.g. optical densities and line sharpness.
Sublimating with Hanrun® at 205°C to 210 °C only needs a transfer time of 25–40 sec. for optimal results.
Depending on the thickness (grammage) of the paper and the application, transfertimes can vary. For detailed recommendation, please have a look at our Instructions for use of each product.
Q:Why is a norm climate within storage and printing rooms recommended for Hanrun® Sublimation Paper?
What effects can occur if you do not comply with this norm climate?
·Positive curl (to the top) e.g. during printing can cause the print head to rub against the paper or, in the worst case, hit the paper and a printer head crash can occur.
·Negative curl (to the reverse side) e.g in the transfer process with a flatbed heatpress can effect, that by closing the heatpress, the heating element hits the paper and bends it, which leads to scrap.
Due to this normal paper behavior, we recommend that the material is only stored in its original packaging and processed under normal climatic conditions (10-30°C, 45-55 % RH).
Q:What influence does a change of substrate have?
The following points affect the result:
·tendency to yellowing
·shrinkage of textiles
·expansion of metal plates
These points must be considered when creating the printing environment.
Q:Why is a fast-drying sublimation paper beneficial?
·As the speeds of sublimation printers continue to increase in the market, it is even more important that the paper has the ability to dry quickly, even without additional heating elements.
·The classic swellable ink-receiving layer shows slower drying compared to a microporous ink-receiving layer, which dries much faster.
·With a fast-drying sublimation paper you have the possibility to increase your productivity and you can save energy costs by lowering the temperature of the heating units or even turning them off.
Q:How can i prevent the paper from curling?
·By determining the maximum total ink coverage.
·Storage and production in norm climate (23°C / 50% rel. humidity)
·Optimal adjustment of the tension in the printer.
Q:Which grammages are available and what do the differences mean?
Depending on the application there are different requirements for the paper:
Fashion / Home furnishing:
·Common grammages: 40 - 60 gsm
·Machine type: Industrial
·Ink quantity: Low
·Special requirement: Maximum running meters per roll
Sportswear / Signage / Universal applications:
·Common grammages: 65 - 100 gsm
·Machine type: LFP / Industrial
·Ink quantity: High
·Special requirement: Thermal adhesive papers for elastic textiles
Hard substrates / Merchandise:
·Common grammages: ~120 gsm
·Machine type: LFP/desktop printers
·Special requirement: Cut sheet / Optimal handling performance
Q:Sublimation with fluorescent inks
What is different from other colours?
·These colours are used as special colours (spot colours). Unlike all other inks, they are ONLY linearized, but cannot and will not be included in the ICC profile.
How can the colors be handled?
·The print data must be created as spot color, then this spot color is replaced by the fluorescent ink in the RIP software with a color replacement.
