I was wondering if anybody has used this or can check it out to see if it makes anything any easier on halftones.. at the link its the one labeled (HALFTONE) Software Download
I am trying to figure the whole "halftone" thing out and ran across this.
Can somebody repost and let me know if this is a good idea to use or not?

Thank you!

Hi,

It is just a photoshop effect, maybe it can be interesting to use it to create a design to print.
But it is useless to use for real halftone if you want to output some film from a complex design

Ok, well thank you! I didnt know and figured I would ask..

Thanks alot!!!

EasyArt Downloads. I use this everyday and it works great. Halftones are a tricky little beast but when you get the process down, you will be a happy camper!!

If you are looking to print halftones, no plugin is needed.

The plug in you posted was to create a halftone effect within a graphic.

To convert a graphic to a halftone, you either need to be viewing a single channel or convert the graphic to a grayscale image.

Image menu --- Image->mode->grayscale

One the image being viewed is a single grayscale channel, you then convert the file to a bitmap.

Image menu --- Image->mode->bitmap

Once in the bitmap dialog, set the DPI to match your printer. For my epson, that would be 720 DPI, under method select "halftone screen"

Within the halftone screen dialog, select 45 or 55 LPI, with an angle of 30,45 or 60 (for a single screen), set the shape to round or ellipse.

The plugin listed can be simulated by converting a graphic to a bitmap, than changing it back to a grayscale or RGB.

I don;t think you need the plugin.

WOW Imageit, you make that look sooo simple! Is it really that easy? I will give it a shot...

Ok so I got it to do the halftones but how do I print it out for sep colors?
All I have at this point is a picture in gray scale with lots of dots making the picture but not sure how to send to the printer for separate colors...
help...

That's it? I thought this halftone stuff was complicated. If I can get this down...then I'd be able to improve my imaging on screens!

Kammo · July 4th, 2008

yeah thats what im saying... but im stuck at the separation part of it. I have PowerRip from iProof but guess its not set up right or something.. still waiting on help for this part.....
Also, I am not sure what the DPI of my printer is.. its the EPSON stylus photo 1400 and everything I look up says 1440 dpi but im not sure if that is what i should be putting in for the dpi or not... If anybody out there knows or could double check that for me that would be awesome!!

Photoshop uses channels to layout spot color separations. Channels are different then layers, in that they are able to assign a color and transparency to the channel.

To create a new channel, go to the channel floating window and select, "new spot channel". In the dialog box which opens, click on th color swatch and choose a color which matches the ink color. For high pigment inks, set the solidity to 90%-100%. The value has no effect on the final output, the value gives of visual expectation on the screen which is the bes guess of the behavior of the actual ink.

Once you setup all the spot channels, move your artwork to the appropriate layers.

Once the image is split into channels, if you have a postscript printer, the channels can be separated using photoshops standard print dialog. The screen angles and LPI can be set with the "screens.." button.

If you don't have a postscript printer, you display 1 channel, then convert that channel to a bitmap and print that channel. Then undo back till you get all the channels back, choose another channel and convert to bitmap and print again. Repeat for all channels

help me for color separation in 4 to 10 color .

The plug-in is actually a work around if you don't have a RIP. It doesn't create a halftone effect in the graphic. You create your color seps in Photoshop and click the button. It creates a halftone bitmap so no RIP is needed. If you have a RIP, you don't need this plug-in.
