Piezography Soft Proofing

Introduction Soft Proof is a feature that has long been used in Photoshop for previewing images as they will appear in print. The “Soft” is for software. Proofs are normally hard copies that are printed to give the designer or photographer and idea of how a digital image will print prior to going to press. The Soft Proof therefore, is a way to look at an image that is being converted by the software (Photoshop, and now LightRoom 4) to simulate the color of the inks, the color of the paper, and the dynamic range of the inks.

Pigment Settling and printer maintenance

Summer time is the traditional time of year when we begin transferring huge quantities of PiezoFlush to our University and High School inkjet customers. Inkjet printers should never be allowed to sit with pigment inks for more than a few weeks, or pigment settling will begin to occur. Schools (and home users) which shut their programs down for the Summer should flush out the printers and allow them to sit with PiezoFlush. This keeps everything moist and ready for the ink recharge in the Fall. One set of large format carts filled with PiezoFlush can be shared amongst printers of the same model. We received requests for 5 liter jugs of PiezoFlush as a result of sharing resources such as flushing carts. Many professional studios use PiezoFlush for routine maintenance. Ever wonder why Epson writes on their ink cartridge instructions that the cartridge should be discarded after six months of use? The ink does not go bad. Ink should have a shelf life for two years or more. What happens is that the amount of ink that has been consumed is too low for the rate of pigment settling within the cart. In other words, if you have not used up an ink cartridge full of ink in six months – then you are not printing at a rate that is high enough to prevent pigment settling. Epson wants...

Epson OEM inks versus Epson 4900 print heads!

This saga of permanently clogged print heads from printing with Epson Ultrachrome inks continues. an opinion When we are contacted by customers who can not free up one or more ink positions in a 4900, Epson inks are always at the cause of this. We still, to this day, do not have any ConeColor or Piezography ink customers who have started up 4900, 7900 ror 9900 printers with our inks and experienced a “permanent” head clog. So, more than a year after we first reported wide spread problems with the X900 printer platform, we are more than a little convinced that the Epson ink itself...

Iceland Piezography

In March, Cathy Cone and I visited Iceland to photograph on the Southern tip of the island. The week’s weather looked good. We were expecting mild weather in the low to mid 30’s f. Light winds. No snow. We encountered an un-forecasted blizzard – not exactly rare for early March. But, it was focused solely on the area in which we were staying to about a 30 mile radius. We have photographed together two years in a row in the rain forests of the Pacific Northwest during December & January. Photographing the landscape in cold wet rain for hours...
