Problems with Fonts

I am having some problems using Corbel font on PageStream.

When I write "fi" or "fl", in the program appears well, but when I
export to PDF it appers "?" or "&;#7923;".

I'm using the last Beta. Any sugestions?

This is caused by PageStream using ligatures and the font not knowing it. I
noticed this recently in some PDFs that I had generated a couple months ago,
but when I tried just now to replicate it I was unable to. I suspect it has
to do with the font handling of the system viewing the PDF -- when I just
tested it was on linux using PgS to generate the PDF and kpdf to view it.
When I saw the issue it was in OS X's builtin PDF viewer (on OS X,
naturally).

To avoid the problem you can instruct PgS to not use automatic ligatures in
which case they will only occur if you specify them. You do so by specyfing
no automatic ligatures under kerning. For the default text setting this is in
Preferences, Text, Attributes. This can be specified in styles as well and
overridden through the kerning dialog for selected text.

Taking the ride, I will ask another question: is there a way of make the
quality of images better? In the pdf they appear very bad...

How so? And again, how are the PDFs being created? If this is the PgS builtin
PDF export then they should be looking the same as in PgS (well, assuming
they are internal images -- if they are external then the image will most
likely be represented in PgS by a reduced resolution FPO in which case they
images should look better in the PDF, but I digress).

Are these images bitmaps? Have they been rotated or scaled? Cropped?

Yes, they are externel images and with no crop.

In PgS they look a little worse, yes, but in the pdf they are very bad too.

What resolution are the images actually at? If they are, for example, at only
72 dpi then they won't look very good.

Nearly all of my bitmaps are done as external images and I don't have problems
with the quality of their appearance, but they were either made or scanned at
600 dpi or greater. Though that is excessive for screen display it does make
for quality output of black and white images to a 1200 dpi laser printer.

I am using png and tiff images.

Can you tell me how can I check the resolution?

No problem. In PageStream select the image and "get information". There is
an 'i' in a circle in the toolbar that I normally use for that, but you can
also right click on the graphic and "information&quot; is the bottom option.

Anyway, in the information dialog one of the entries is "size". For
example, "Grayscale 1388x1428x8 2009k";. The 1388x1428 says that the image is
1388 pixels wide by 1428 pixels tall.

With the image selected the Edit palette will show the width and height in
inches (or centimeters, or whatever you have configured). DPI (dots per inch)
is in inches so for comparison to the "standard" numbers I will use inches.
In the case of the graphic I mentioned above it is 2.2875&quot; wide by 2.4625&quot;
tall. This gives 609 pixels per inch wide and 580 pixels per inch tall.
Either I inadvertantly distorted the image at some point or that is an
artifact of the masking.

Anyway, for a black and white graphic pixels per inch is the same as dots per
inch. This gives about 600 dpi. Compare that to:

72 dpi -- this used to be the standard for screen graphics (e.g., web images)
96 dpi -- this is what many LCD monitors are (I usually just round it to 100)
300 dpi -- old laser printers
600 dpi -- many laser printers (though the issue is confused by dots per inch
resolution versus the size of the dot, a similar issue exists with inkjets,
but is much more exaggerated there)
1200 dpi -- a high quality laser printer

As a rule of thumb I would not expect anything less than 100 dpi to "look
good&quot; on the screen. Printed black and white needs to be at least 300 dpi and
preferrably more. When printing non-black and white images it gets more
complicated depending on the print method and resolutions. For example, I
output to a 1200 dpi black and white printer so gray scales are achieved with
around 180 lpi -- that gives reasonable resolution with sufficient scale to
be tolerable. "lpi&quot; refers to "lines per inch" and has to do with the screen
used for printing (though at this point I'm starting to get out of my depth
in printer terminology).

I am going to be honest: I don't understand that method.

I change an image in GIMP to 600 DPI. To me, the difference was few. The
images keep poor.

You can set a DPI in the gimp, but that is just a "suggestion"; -- it has no
real meaning. DPI, dots per inch, is (for a black and white image) the number
pixels per inch.

So if you have a 600x600 pixel graphic in the GIMP and set it to 600 dpi there
the picture stores information that it should be displayed/rendered at
600dpi. But when you import it into PageStream the graphic occupies a certain
size. This is the meaningful part because if the graphic is sized to 5"x10"
then it will print at five by ten inches.

If your original graphic were 600x600 pixels and you sized it to 1" by 1" in
PageStream it would be 600 dpi. But if you size it differently then it is
different.

For a 600x600 pixel bitmap:

Height Width x DPI y DPI
1&quot; 1" 600 600
4" 4&quot; 150 150
5" 6" 120 100

That is why I said to take the dimensions from the Edit palette in
PageStream -- that is the easiest way to get the printed dimensions of the
graphic. The DPI setting in the GIMP is a suggestion and has no real meaning.
