2. Museum-wrapped (Other term: Solid-Color)
Canvas Print Museum Wrap
Printing Method:
Pigment-based Ink

The Pigment based ink solution gives longevity. It is thus no surprise that many printers are opting for such pigments. Manufacturing costs are higher, therefore cost of the ink is higher to the user.Degradation of pigments by pollutants or ozone is not that much, the presence of the resin coating limiting it further. Color density is generally better, or easier to achieve than with dye-based inks. However talking of limitations pigments shows tendency to promote a defect called bronzing. When brightly lit or if lit with low incidence, the print can show unpleasant metal-like reflections.

The technology of pigment is comparatively difficult to master as the problem of small size of the particles to create in large quantities must be taken into account. As nano-sized particles have to be manufactured that will be coated in a thin resin. This resin is used for protection of the pigment against external chemical and mechanical attacks. This has a problem too as it also helps in transportation of the particle inside the ink, through the nozzles and finally onto the paper. Thus it is quite clear that these contradictory constraints make this technology a difficult proposition to perfectly master.

Dye-based ink

The dye based ink is usually cheap though the manufacturing cost is only one factor in ascertaining the selling price of inkjet ink.Dye is usually fragile, when exposed to light and Ultra-violet light, the colored molecules gets broken and loose its color. This results in the prints to loose their original colors and fades overtime.Ozone and several other common pollutants are also able to chemically break down the color molecules.Drying time has a direct bearing with the drying time of the solvent on the paper (often this leads to untimely closing of nozzles, if the ink is set to dry very fast on paper). Consequently, if the ink and its solvent is not quickly absorbed by the paper, there is a risk of ink flow or paper deformation.

Dye inks are prepared by dissolving of the liquid colored dyes into a fluid carrier. This makes the dyes easy to apply. When it is applied to a paper, the dyes are absorbed very uniformly so they reflect light very evenly. As the printing is a high precision job the inkjet dyes need to have superior quality in terms of colors, physical properties, and stability. Generally direct, reactive, and acid dyes are used as dyes for Inkjet Ink.

Inkjet dyes have many advantages, some are listed below:

  • Stable and soluble.
  • Wide array of colors.
  • Bright intense colors.
  • Wide selection.

  • A few of the drawbacks as experienced by the users of the inkjet dyes in the printers is given below:

  • More damage prone to attacks of sunlight ozone and ultraviolet rays.
  • There is a tendency for less stabilization.
  • The print is not as much thick as of a pigment based ink.
Stretched Canvas Components:

Stretched Bars

A stretcher bar is used to construct a wooden stretcher frame used by artists to mount their canvases or by canvas printers.They are traditionally a wooden framework support on which an artist fastens a piece of canvas. Stretcher strips can be made from wood, metal, or a combination of the two. Cross braces are used to provide additional support to the frame, to keep it square, and to help prevent warping and twisting.
