Objective: By the end of this lecture, the student will be able
to import circuits and plots from PSpice into MS Word
Sec. 9.1 A word about the programs
This lecture is strictly for students who want to dress up
reports. This includes adding pictures of the circuits and the plots
from PSpice and incorporating it into Word. The reason I use MS Word
is that it is the program most people have. Also its the program
that I use so I am the most comfortable using.
In addition to MS Word, I also use other programs to enhance
the images from PSpice. The programs I used are:
- Adobe PhotoShop 5.5
- Micrographx Image 1.0
- Micrographx Picture Publisher 8.0
- Adobe Illustrator 8.0
- Macromedia Freehand 9.0
Although it is not necessary to use these programs to import pictures
into word, it is recommended that the students get familiar with them.
Adobe PhotoShop, Image and Picture Publisher are raster graphic
programs. This means these programs handle all the image types as pixels.
This basically means these programs are generally used to enhance an image.
The limitation of these programs is that when resizing an image, there
is a lost of details. The other disadvantage to these programs is the
price tag. PhotoShop cost around $400 and Image cost about $200.
Adobe Illustrator and Freehand are vector graphic programs.
This means the programs represent images with mathematical equations,
thus when the image is resize there is no lost of details.
I generally use PhotoShop and Image if Im in a rush
to create images to be used in Word. If I have more time, I would use
Illustrator or Freehand to create the images.
A final note on the programs; PhotoShop is the industry standard
for image manipulation. Illustrator and Freehand are both highly regarded
in the industry. So it is a good bet that if you ever need to create
some pictures for your report or presentation at work you would most likely
encounter these programs.
Sec. 9.2 Importing pictures into PhotoShop
- Create a circuit in Orcad Capture
- Press Print Scrn button on the keyboard to put a image of the
desktop into the clipboard
- Open Adobe PhotoShop
- In PhotoShop click on File/New
- Accept the suggested image size by clicking OK
- Click on Edit/Paste
- A new window will open with the image of the desktop, refer to fig.
9-1 for the screen shot
- Select the rectangular marquee tool
- Create a selection for the figure
- Click on Image/Crop
- If there is two layers, click on Layer/Merge Down
- Click on File/Save As
- Select TIFF as the output file options.
- Go to MS Word
- Create a 2 by 2 table (I have found using a table would allow easy
formatting)
- Click on Insert/Picture/From File
- Locate the file and click OK
This is the step I would used in Adobe PhotoShop. If this way seems
cumbersome, instead of pressing Print Scrn on the keyboard, you
could just select the portion of the circuit in Orcad and copy it into
the clipboard. Then using the same procedure, create the image.

Another way of importing the circuit to Word from Capture
is to just highlight the circuit the copy it to the clipboard. Go to
Word and paste it from the clipboard.
Sec. 9.3 Importing data into Illustrator
- Create the circuit in Orcad Capture
- Select only the portion of the circuit that is needed
- Click on Edit/Copy
- Open up Illustrator
- In Illustrator, click on Edit/Paste, refer to fig. 9-2 for
a the screen shot
- Resize the image to the size you want
Its a good idea to turn on the ruler so you can see how big the
image would be
- Click on File/Export
- Select TIFF as the output file type
- Select High as the output resolution with anit-alias
and LZW Compression uncheck
- Follow the same procedure as in sec. 9.2 to place the picture in Word.
It would seem redundant to use Illustrator when Photoshop does the same
thing. But the one advantage to using Illustrator is that you can resize
the picture it would still look good, while the picture would look very
bad if resize using Photoshop

Sec. 9.4 Getting the plot from the Probe window.
- Create a circuit in Orcad Capture
- Simulate the circuit
- In the Probe window, click on Window/Copy to Clipboard
- Select the options as seen in fig. 9.3
- Place the image in MS Word by clicking Edit/Paste

Sec.9.5 Comparing the output results
There is a lot of way to generate the pictures to use in
Words, the appendix for this lecture shows the different output using
different methods.
Tips for importing pictures
I will always use Illustrator as oppose to PhotoShop
if I have a chance. The output always look better. If you must use a
raster base graphic program, follow these little tips
- When pasting, choose a dpi of at least 120 150. This range
of values provides the best printing results. All the images made in
this workshop are 150 dpi
- Always save the image in TIFF format. TIFF save the image in a lossless
compression scheme. This means the image will be preserve in the exact
way as shown on the screen.
- Avoid using GIF format. The GIF format will create a smaller file,
but it is limited to 256 color
- Avoid using JPEG. JPEG is a lossy compression scheme. A lot of information
is lost in saving the file but the file size will be smaller.
- If the computer is slow, avoid using the Print Scrn option.
This takes up a lot of memory and processing power.
For a vector base graphic programs, follow these tips
- In Windows 2000, do not paste anything from Orcad Capture to Illustrator,
it will crash the program. Windows 98 does this perfectly.
- When pasting into the programs, the objects are group together, so
it would be necessary to ungroup the objects.
- Avoid inserting the vector file into Word, the image quality is never
that good
- When exporting, use at least 300 dpi. If possible, use 600 dpi.
PhotoShop Output
Photoshop allows the pasting of the images in different dpi.
Below are the images pasted in PhotoShop and place in Word using different
dpi. All the pictures were saved in the TIFF format.

Illustrator output
The outputs from Illustrator offer more options. These options
give more control when creating the images. Also note that when the image
is resize, there is no degradation of the image.
