When the ink is very high viscosity, when it is barely shear-thinning or exhibit psuedoplastic flow, the mesh may not have sufficient volumetric capacity and the stencil only affects the detailed areas of the image. The flood-bar can be used to pre-load the cells of the mesh with ink prior to the print stroke providing the ink transfer is based on sustainable volume (extrrusion) and is not based on minimum velocity or momentum (ejection).

Control of the ink deposite is also directly affected by the stencil with regards to printing a non-porous substrate. >Granted the flood bar is an important part of the printing process on non-porous substrates but I believe that more important is the viscosity of the ink, screen tension and the mesh count.

It has been a long time since I have heard somebody talk about new year with such passion. I didnt quite understand everything but the passion flows throughout the and it is amazing to see someone be so in depth about something. I can feel it, if that makes any sense. >wow!

I have noticed a change in the economy and I hope that it continues to turn throughout this year and further on. Preparing for recovery sounds like a very effective plan in helping one's business. In our Social Media class we have been learning about the importance of networking to build relationships--through blogging, microblogging, podcasting, etc. Do you use any other social media tools? >Hi, my name is Stephanie Rowe and I'm a student at Ohio Northern University.

http://www.happcontrols.com/images/pdf/rohs_directive.pdf

The exemption paragraph is numbered (11) and starts by stating;

Exemptions from the substitution requirement should be permitted if substitution is not possible from the scientific and technical point of view…

and this pdf document (click on the Mercury exemption link);
http://www.rohs.gov.uk/content.aspx?id=15

Line 4 is applicable in this case;
4.Mercury in other lamps not specifically mentioned in this Annex.

The RoHS Trade Directive, while not exempting the lamps specifically, has allowed exemptions for both processes that have no technically feasible component substitution and for the allowance of mercury in other specialty lamps.

The language is typical of this type of document, strict in parts, but fuzzy or ambiguous in others. I hope this helps you out.
