2 color logo screen

[pgween1]

I have a logo that is type with a screened inside. kinda like its chrome type. the lettering goes over a silver 877u.


I saved it as a 2 channel dcs.

my rip keeps makeing the solid around the lettering a screen. i havent had this problem before, I made and remade the file several times getting the same results. Ive made the file a black and white tiff and in quark i made the picture box 877 and the tiff black and still. its screening out the black solid around the type.

in photoshop ive made sure that the color is a solid black (ie: paint bucket)

and ive made the black a spot channel. (process black-magenta-072 ect.)


i cant seem to get this file to rip right. i had the same type of file last week and it ripped fine.

confused is there something im doing wrong?????

i have mac 10
photoshop cs and quark 6.1 im running a halequim express rip ect.

confused
any help would be nice.
thanks

If its not a massive file, why not try and send it to me and I'll see what happens on our RIP, see if we can't come up with something.

Well when i originally received the file it was a black and white illustrator 9 file.

i have the logo in photo shop on separated layers. "ie: logo that is black and white and a layer that is 100% black in cmyk)


what its doing is making the black a rich black.
my question is....


is there something in the data of the file thats defaulting it to rich black?

s there a way for me to change the mode or save the file down to remove the defaulting rich black?

ive converted it to gray scale and saved it as a tiff and then reopend the file in photoshop and change it to cmyk. then change it back to cmyk highlight the area thats going to be silver and making a spot channel that is silver.
then high light the black back ground and makeing a channel thats 100% black.
saving it as a dcs eps and reopening it in quark.
Ive opened it in in design and still the same result. ( rich black)


is there a way i should be doing this.....

its not a big job so im just going to burn a fatty on the light table to trap out the silver fill, opaque the screen around the logo ect.

Generally when you open a file from another program in Photoshop it'll always change 100% black into a 4 colour (default black). Its just a case then of then going into each of the separate channels and changing them, but it kinda sounds that thats what you're doing. Just make sure that you've gone into the actual black channel and made that 100% and deleted it from the other channels. That'll make sure beyond a doubt that it is solid.

It also sounded like you were using a process black separation, just use the default black channel, theres no need to make it more complex than it already is.

Like I said before I don't mind taking a look at it for you.

thanks weasle


i ended up getting it off.i just was missing something yesterday.
dunno what.
nother day
nother job

just another question.
is there a way to get crisp edges in a dcs file?
it always seems to screen / dot out the edges of the images. nothing too noticeable well.....
i notice it and even on other printed material notice it.
is there any way to get it crisp?


ie: if i take a vector image from illustrator and take it into photoshop and make it into a 2 color dcs it makes the edges not so crisp. even o n vertical and horizontal lines.

just curious

turn off the "Anti-aliased" feature in the main tool bar. this softens the edges of almost any tool you use.

Why are you converting the Illustrator graphic to Photoshop to begin with? The Illustrator file will have the crisp edges you are looking for.

[beermonster]

you can copy paste as a smart object in photoshop cs2?it will keep it as a vector so you can re-size and do whatever.


from the 4 colour black it looks as though the actual "black" may not be 100% - ie: after removing cmy its a tint/screen. You could, with a new layered photoshop file (having removed cmy/edited logo to give desired result) have 4 layers.

1> background
2> silver with knockout area and trap
3> logo
4> draw the area that is causing the problem?stroke with solid black over the top - this means it now HAS to be solid

rip it?and pray

on the other hand?if it's an illustrator image opened in photoshop i bet ya opened it at 300 dpi didnt ya? this will cause the edges to bitmap slightly or maybe look screened?try it at say 1200 or higher.

the best way is as a smart object in photoshop cs2?or keep it as an illy file as said previously
