Screen Printing - April/May 2013. Halftonedefstudios' Photostream. Choosing LPI For Output. This is a very, very common question and there's usually some "machoism" associated with it.
You know, I can print 85 lpi all day, and so on. Here are some things to consider. Just because you can print a finer dot, doesn't mean you should. This will be the first of several posts on choosing lpi based on production considerations and related factors. The choice of LPI for your halftone is determined by several factors. Substrate Limitations.Viewing Distance.Screen stencil resolving capabilities.Production variables (mainly moire and dot gain.) The coarser the dot you choose, the easier it's going to be to make an accurate stencil, control moire, dot gain, and tonal range reproduction. On the flip side, the finer the dot, the more detail you can hold and the less noise the image will have (surface texture that interferes with the image.)
For textiles, the most common ranges fall between 45 lpi and 85 lpi. First and foremost, consider the "dot density". The dot density is the lpi squared. Ellipse Vrs Dot shape benefit "example attached" [I believe that one the underlying problems is that the ratio isn't "really" changing, just the shape of the dot within the cell. Attached is shape i've created, but have not had the time to test. This example is a round dot halftone at a 2:1 film ratio.
This results is elliptical dots oriented to the horizon (regardless of angle). The horizontal elliptical dots are intended to counteract textile moire. Rather than a 45 LPI or 55 LPI, the halftone might be 60 LPI in one direction, while 30 LPI in the other, or a 50/25 lpi. This is an interesting example. For simplicity sake, let's assume the halfone line count is 50 lpi and the output resolution is 600 dpi. You are correct in describing a different apparent resolution in one direction over the other.
This is why moire is so common in highlight and quarter tones. The way the dot builds inside the individual cell is determined by the Postscript Spot Function.

Trying 85 lpi 4 color process. Doing some quick and dirty math, at 85 LPI one "cell" for a dot is about 300 micron square, and isn't 3% @ 85LPI a less-than sixty micron dot? I'm not sure what you mean by 85lpi (cell). Are you referring to mesh opening or the cell used (in your printer) to plot out how many spits of ink onto the films in a given location to fill the needed space to make up a dot? Most "digital printers" are not 100% accurate when outputting dot %. So, the typical digital films 85lpi 3% dots might be as much as 50% larger that a "real life" 3% dot.
Then again, what is "real life". The 420-30 Murakami smart mesh has a 30 micron thread and a 30 micron opening and results in a 25% open area (so they say). Not that you'd measure this all that accurately, but your smallest halftone dot would have to be in the area of 2 mesh threads and one mesh opening to (get as much tonal range as you can get). Now, once you've done that, you will realize that yes, your holding a very fine dot but then, what next? Pdf_server.cfm (Objet application/pdf) SkatRadioh's Photostream.

Four-Color Process Printing | Printwear. If you’re either very new or very old in this business, you’ll have come across four-color process (4CP) printing. For those who are very experienced (20 years or more), 4CP or CMYK printing was the only real way of achieving photo-realistic reproduction. For more than 150 years, this was the way all full-color printing was done for all printing processes. 4CP history Right from the beginning, I’d like to clarify a major misconception about process color. A healthy human will see somewhere between six and 10 million colors and tones depending on age and gender. For those new to the industry, CMYK or process color reproduction is experiencing somewhat of a renaissance. All digital printing is CMYK or true process color reproduction. For inkjet or digital reproduction, it’s very common to have even more.
Controlling the process The goal of any type of halftone printing is to recreate various colors and tones through the use of printed halftones. Mesh specification Mesh Tension Squeegee angle. Are water based inks REALLY more environmentally friendly? - Screen Printers Open - A Forum for Screen Printing and Embroidery. No, water based inks are not more environmentally friendly than plastisol. The history of water based inks, was as a replacement or solvent based inks. This primarily involved paper printing. When printing a product, such as newspapers, the ink is predominantly a solvent and is consumed by the barrel.
Each gallon of solvent was released directly into the air as a result of the drying process. An example, 250,000 pounds of 1,1,1-TRICHLOROETHANE, 12,000 pounds of MEK and 10,000 pounds of TOLUENE in a year. In this context, water based could be debated to be more environmentally friendly. Separate from green, another big issue with printing was "food safety". Since the printing industry had gotten such a bad name for the use of solvents and unsafe pigments (lead), people came to believe that "water based" and "soy" must be better. The curring of plastisol is a chemical reaction, not a matter of any solvent. A ? Fred. Contact & liens - jeronimo.dk. Amélie Graphiste. PAN!
