Tables Summary Slide Format Background for Slides Use a dark background,
such as shown here. Dark blue is most easily viewed by most people and recommended. Text Font and Color Use the largest size fonts that fit with the space on the slide. Use bold font styles. Yellow or white font color is
recommended. Text Font and Color Never use red on a blue background like this. Text Font and Color Remember that many in the
audience will not have perfect vision and some will be color blind. Plan for a large presentation room. Use large bold fonts that will be visible from all parts of a large room. Text Font and Color An example of poor font style An example of poor font size
An example of poor font color An example of poor font color Company Affiliation Do NOT place your company name or logo on the footer or header of the slides. Company names and logos are only to be on the first slide.
Reference to any specific commercial item is to be made generically for the rest of the slides. Commercialism To say the least, it is very poor etiquette to deliver a sales pitch on the pretext of a technical presentation.
Transition Slides Transition Slides Transition slides like the previous slide provide a great way to inform the audience of a topic change. Use keeps your audience focused.
Graphs Graphs Convey numerical information with the minimum amount of detail. Make graphs large enough to be easily seen anywhere in the room. Graphs
Instead of a legend consider using text labels. Use bold type and large symbols. Graphs Use different line patterns, line thickness, and symbols to distinguish data.
Example: Poor Graph Figure 4. Extrusion rate for three screws. Example: Good Graph Screw A Screw C
Screw B Diagrams Diagrams Diagrams are excellent for clearly showing the pertinent details of the object of discussion.
Diagrams Leave plenty of time in your presentation for the audience to become familiar with your diagram. Over a minute is not too long. Example: Poor Diagram Hopper
Screw Cooling Channel Feed Casing Barrel
Ledge Plate Discharge Assembly Figure 3. Schematic of the solids conveying device with the ledge plate installed. Example: Good Diagram Hopper
Screw Cooling Channel Feed Casing Barrel
Ledge Plate Discharge Assembly Tables Tables
Tables should be used for information that is not numerical. Example of a Table Resin Colors RESIN Red
Blue White PP Yes
Yes No PET No No
Yes PE Yes Yes
Yes Nylon No Yes No
Tables Avoid the use of tables for numerical results. Use a graph instead. Rates for a Mixture of Commercial PS Pellets (An Example of a Poor Table)
Screw Speed Rate, kg/h Specific Rate, kg/h Temperature, C rpm Screw A Screw B Screw C Screw A Screw B Screw C Screw A Screw B Screw C 30 45 60
51 1.5 2 1.7 250 232 240 50 75
100 85 1.5 2 1.7 252 234 242 70
105 140 119 1.5 2 1.7 254 236 246
90 135 180 153 1.5 2 1.7 256 238
250 The next slide illustrates the trend of these data much more readily as a graph. Graph of Previous Table Screw B Screw A
Screw C Equations Equations Use equations to illustrate physical phenomena, and graph them if possible.
Use only commonly accepted nomenclature. Equations Refer to your paper for complicated mathematical developments. Equations must never demonstrate an exercise in algebra.
Equations Poor Example n d 2s n n m s 2 h d
2h n n (1 n ) ( 2 s ) ( h) a m
n 1 2 n 2 (n 1)h ( 2 s ) n ( h ) n 3 n FN m n 1 2 n 2 (3 n)h
1 n Equations Good Example 2 ( n 1) / 2
o (1 ( ) ) and n are constants. Equations Assumptions and conditions that make your equations accurately
capture the essence of a process (with results) will be much more useful to a general ANTEC audience rather than a mathematical Photographs Photographs Photos should be:
uncluttered, well focused, and well lighted. Photographs Ideally, the subject should be isolated against a plain background. If not, the subject should be obvious and distinct.
Photographs Sometimes it is appropriate to use a familiar object (e.g., a ruler) in a photograph to establish dimensional scale. Photographs Labeling (e.g., with balloons) is
recommended to point out important aspects of the subject. Photographs - Good Example Barrel Single-Screw Extruder Hopper
Content Content Keep the content of the slides close to the content of the paper. Content The best presentations generally teach
the audience an important and useful aspect of your topic. Provide useful conclusions and recommendations that are backed by quality data. Content State the goals of the presentation at the start of the talk.
Slide titles should follow the paper sections. Introduction Materials Equipment Results Conclusions (or Summary) Content Present the minimum amount of information
on the slides needed to clearly introduce and outline your ideas to the audience. The details of the work should be in the paper, part of your supporting discussion, and used to answer questions. Tips Tips
No more than three key sentences or statements are typical on a good single slide. Tips - Slang Slang words are not appropriate for technical presentations. Slang words can mislead the audience. They create difficulties for our non-US
colleagues. Tips - Slang Slang The temperature of the first barrel zone was dropped to 230oC. Correct The temperature of the first barrel zone was decreased to 230oC.
Tips - Abbreviations Use only standard abbreviations. Do not use numerous abbreviations. Tips Poor Abbreviations Example The super-duper plasticating extruder (SDPE) is shown by Figure 6. This SDPE worked well
for LDPE. The audience will quickly loose interest if they need to learn and translate numerous abbreviations. Tips Good Abbreviations Example The low density polyethylene (LDPE) used had a melt index (MI) of 2. The
comparative LDPE resin had an MI of 3. Tips - Write Now Guide Many great presentation tips are given in the SPE Write Now Guide. A copy of the Write Now Guide can be obtained at: www.4spe.org/sites/default/files/write-now09.pdf

A well done presentation will be an enjoyable, rewarding and lasting professional moment. S. J. Derezinski and M. A. Spalding
