    I must say that your service is absolutely exceptional and I have recommended your company and products to several friends today; all are serious "printer" people.I retired last year and my friends are all into, or are still working in the photo industry. Sincerely,Gerhard


    Dear, just to let you know than i realy appreciate your costumer service.
    Thank you


    Just a Thank you and all the best


    Ce message est simplement pour vous dire que j'ai bien reçu la commande XXXXXX et que je suis très satisfait de la rapidité de la livraison et aussi de la qualité de l'encre. C'est la première fois que j'utilise de l'encre "autre que l'originale" et pour le moment je suis très satisfait. Soyez certain que je vais vous référez à mes amis et collègues de travail et c'est certain que je vais commander à nouveau de chez vous. Merci beaucoup.


    Je veux seulement vous dire un gros merci pour la rapidité avec lequel vous avez traité ma demande et aussi pour le petit extra en papier photos,c'est très apprécié.



    I received my order, thank you for your great customer service..



    It is not often people write emails or letters of praise but consider this one of the rare ones!
    I must say, ordering your product was about the easiest imaginable. Coupled with the fact that it arrived here basically “next day” I am thoroughly happy. To tell you the truth, I was expecting to have to go pay full retail for one black cartridge thinking that your’s would take at least a week to arrive but I was wrong, the order arrived before I could even go out to get one!
    Congrats people, I WILL tell all my friends and neighbours about you!

Inkjet Printer,a Goat, and Horseradish

What do all these items have in common ?

Piezoelectric inkjet printing of a cross-hatch immunoassay on a disposable nylon membrane.
Yup that’s a mouthfull…

The development of a cost-effective method for manufacturing immunoassays is a key step towards their commercial use.

In this study, a piezoelectric inkjet printer and a nylon membrane were used to fabricate a disposable immunoassay.

Using a piezoelectric inkjet printer, a cross-hatch pattern of goat anti-mouse antibody (GM) and rabbit anti-horseradish peroxidase (RHRP) antibody were deposited on the nylon membrane.

These patterns were subsequently treated with a solution containing rabbit anti-goat antibody labeled with horseradish peroxidase (RG-HRP).

The effectiveness of the immobilization process was examined using tetramethylbenzidine (TMB), which oxidizes in the presence of HRP to form a visible precipitate. Optical evaluation of the TMB precipitate was used to assess the precision of the features in the inkjet-printed pattern as well as antibody functionality following inkjet printing.

Uniform patterns that contained functional antibodies were fabricated using the piezoelectric inkjet printer.

These results suggest that piezoelectric inkjet printing may be used to fabricate low-cost disposable immunoassays for biotechnology and healthcare applications.
