Best Solutions

Visual logic lies equal distance between the visual elements and the logical elements. Visualogic is a term that describes how a person best uses the visual and logical aspects of typography to make a text both accessible and beautiful to the reader. The best solutions to the conflict involving the eye and the intellect lie somewhwere between the two, in the middle of the spectrum.

You must now use the symbols for typeset documents. Sometimes an em dash simply is too long, so use an en dash. Hyphens are used to hyphenate words.

Legibility

Definition of Legibility: How well a

typeface supports the processes of

fluent reading.

• The easiest checks on legibility are those at the character level.

• Checks on characters in context give a better feel how a typeface will work when it is being read.

• Legibility checks must be done on paper since screen resolution is too course.

• Give your readers a choice between two typefaces, and ask them for their preference in terms of readability.

Legibility: Character Level

• Check typefaces for any quirky characters that may catch the the reader’s attention, giving unintended emphasis to certainwords using that character.

• Check for characters that are likely to be confused with one another, bearing in mind the context of the character.1. The numeral ‘1,’ the capital letter ‘I,” and

the letter ‘l’ are often confused. 2. Some reversed letters at lower

resolutions are often confused.3. Some italic letters are often confused.


Sans Serif Type:

Without Tails

Bagging Baseline

no tail

Descender Height

Ascender Heightx-height

•The x-height itself may not be the sole contributor to legibility. Typefaces with large x-heights often have wider characters and may also require more vertical space than typefaces with small x-heights. •Typefaces with large x-heights appear larger and, thus, reproduce well in printing and photocopying.


Serif Type: With Tails

Bagging Baseline

tailDescender Height


•The x-height itself may not be the sole contributor to legibility. Typefaces with large x-heights often have wider characters and may also require more vertical space than typefaces with small x-heights. •Typefaces with large x-heights appear larger and, thus, reproduce better in printing and photocopying.

Legibility: Word Level

Vertical Dimension

Bagging Baseline

tailDescender Height


•Check that there is enough difference between x-height and ascender height for overall word contour. Too, clarity of word contour willdepend upon the vertical spacing provided.


Horizontal Cohesion

• Check the lateral spacing of a sample text. Characters should not be colliding with each other or be so far apart that they appear to be two separate words.

• Reversed type often appears cramped without lateral adjustment.

• Small capitals appear cramped without lateral adjustment.

• Some bold typefaces have disproportionately large word spaces.

• Justified text has less consistent character and word spacing than does ragged text.


Horizontal Cohesion• Warning: If you are using tracking or

letter-spacing to make global adjustments, global alterations often improve somecharacter combinations but not all.

• Kerning can be used in your program to improve letter combi binations that are too loose or too tight. Kerning is especiallyuseful in titles and headers, where the type size is larger. You must remember that certain character combinations are naturally widely spaced, e.g. ‘vy’ and ‘ry.’ Kerning will only make them touch.

Legibility: Context/Document LevelTo differentiate and emphasizeelements of a document and yet haveunity sounds contradictory. But typeface families are designed to do that. • Documents usually comprise different

elements, such asfootnotes, formulae, captions, index, headings, and so.

• Some of these elements need to be differentiated typographically, not just by their content or position on the page.

• Some of these element sneed to be emphasized typographically in relation to other elements.

• Simulanteously, different elements of a text should form a visual unity.

Legibility: Context/Document Level

One or Two Typeface Families?

• If one typeface can adequately distinguish all the necessary elements of a document, then use only one typeface. Different text elements set in regular, italic, bold, condensed, or other variants of one typeface should be quite distinguishable but related in style.


One or Two Typeface Families?

• Sometimes one typeface family cannot represent all the necessary elements. Then you will need to com-bine two, but rarely more than two, typeface families in one document.


Two Typeface Families in a Document

• The effectiveness with which two typeface families work together depends partially upon the features of the characters, i.e. they must be quite dissimilar in appearance:– Serif or sans serif– Degrees of contrast in heights and

widths

Serif San Serif

page pagecontrast in thicknesses no contrast in thicknesses

light weight light weightnot wide widenot so high higher


Differentiation with Emphasis

• Necessary in the heading structure of a text or to draw attentionto particular text elements– First consider variant of main text

face– Necessary high resolution for printer

(c. 640 dpi)•There should always be more vertical space above a heading than below a heading.


Differentiation Without Emphasis

• Combine typefaces that contrast in style, not size, width, or weight.

• Combine typefaces of different scripts• Combine text typefaces with symbols,

but be careful of thevertical height

Legibility: Context/Document L Level

Main Variables of Documents

Affecting Individual Typefaces:

• Vertical spacing• Type size• Word spacing• Line length


Coordingating Typeface and Document Format

• Vertical spacing should be adequate for text contentand typeface.

• Horizontal spacing, justification mode, and line length should be adjusted to give evenly spaced text.

• Look at the relation of the text area to the page as a whole.


Spatial Relationships Between Text

and Page• Do not attempt to set any typeface to

the format of a typewrittenpage. The pages of text will appear dense and unappealing.

• Do not use the default setting for line length for line length.– Text at large page sizes should be

surrounded with a lotof space or set in columns.

– Text in a single column on a page should have wide characters.


Matching Typefaces to Document Genre (Top Down)

• Consider the conventions of the document to be produced.

• Avoid too much formality.• Conventions should be

appropriate to the typeset, printed document, not to a typewritten document.


Appropriateness• Use Orator

– For highly legible lecture notes– For simple legible type– For tabular charts where character

alignment is needed

• Test the typeface in your document.• Use New Century Schoolbook

– For lengthy text applications.– For adverse printing conditions.– When maximum legibility is

necessary.


Formality vs. InformalityHigh contrastsSoft ContoursFine details

Vertical or regular letterforms

• Reduce level of formality

– with an asymmetrical page format.– by ragging, rather than justifying, the

text.– by not using capitals in headings.

CHARLEVOIX, MICHIGAN WATERSUPPLY SYSTEM IMPROVEMENTS

INTRODUCTION

The purpose of this investigation was to review the adequacy of the presentCharlevoix water supply system to meet present and anticipated future waterdemands of the community. The present system was installed in 1922, whenthe permanent population of Charlevoix was about 2200. The population sincethen has doubled, and recent projections indicate that the population willdouble again by the year 2000.

The following questions therefore arise:

1. Does the present system have a maximum safe capacity to meet projected water demands?

2. Are the pumping, distribution, and elevated storage facilities capable of meeting projected demands?

3. Are these facilities capable of meeting recommended fire flow for the projected population?

The present system also lacks the disinfection facilities now required by the State for all municipal water supplies.

To evaluate the adequacy of the present water supply system in the face of future demands, the study uses population projections to establish futurerequirements and analyzes the capacity, equipment, and facilities of the presentsystem. A comparison of future requirements with the abilities of the present system. A comparison of future requirements yields the recommendations forimprovements of the Charlevoix water supply system.

We use existing records, field studies, and earlier engineering reports todetermine the needs of the water system. We review all general areas of the present system plus some additional construction to bring the total system upto levels sufficient to meet anticipated requirements. The report presents the

estimaed total cost of the projects and a breakdown of costs for reach part of the project.

The report is divided into the following main sections:

I. WATER SUPPLY REQUIREMENTS. This section analyzes the trends of population growth, pumping patterns, and per capita consumption in order to project future design flow requirements.

II. THE PRESENT WATER SYSTEM AND RECOMMENDEDIMPROVEMENTS. This section compares the future requirements withimprovements.

III. COST ESTIMATES. This section itemizes the estimated costs for theimprovement recommended.

Subject: Proposal to Introduce Line Heating Technology into ASBC Production

Procedures

At present time, the technique of cold-forming shell plating limits our productivity

and flexibility. The fact that we rely on this technique limits our competitiveness in

some bid situations. I therefore propose that ASBC introduce line heating technology

in our facilities, and have scheduled a meeting on 16 July 1986 to discuss this proposal

and its implementation. I believe this is an important matter, as line heatingtechnology

will enable us to stay competitive with other U.S. shipyards.

Line heating technology will (1) increase our productivity, (2) facilitate more complex

shell plate curvature and lower costs, and (3) improve production flow. Improved

fabrication quality will result in the yard being more competitive. Implementation of

line heating technology will require approximately one year, including planning.

Limitations of cold forming technique. Our facilities for cold-forming shell plating do

not suit the the needs of current designs. These facilities can perform adequate shaping

only up to 3/4 inch thick plate and are not capable of giving plates longitudingal

curvature. The specifications of our cold-forming facilities and optimal specifications

for contract TY 236-83 are listed in Appendix A.

Line heating technology. Line heating is the process of inducing curvature in structural

shapes and plates by controlled heating and cooling. The process is also scientifically

applied for fairing structural intersections and removing distortion due to thermally

induced stress.

Advantages of line heating for forming curved shell plating. By utilizing line heating

technology, we can eliminate the restrictions we now face in the forming of shell

plating. The advantagaes of line heating are:.

1) Increase in productivity, as seen in other U.S. shipyards (Appendix B).

2) Ability to accurately form shell plates with compound curvature (Appendix Citemizes parameters and dimensional control for plates on Hitachi Hull Y-14-2),which results in a cost savings.

3) Ability to accurately fit curved parts to curved shell with minimal force, whichrequires fewer man-hours than cold forcing.

4) Accommodation of larger plate sizes, thereby minimizing butts and seams.

5) Optimization of existing facilities through improved scheduling and elimination of bottlenecks.

6) Facilitation of subsequent assembly by eliminating distortion prior to forwardingan interim product to the next level of production.

7) Ability to accurately and productively fair structural intersections.

8) Enhanced worker safety.

Our statistical accuracy control system would be modified to assure the normal

process capability, including standard range and tolerance limits.

In conclusion, line heating shapes material more accurately with less effort and

provides more production flexibility.

Implementation of line heating. Introduction of line heating would be best

accomplished by contracting with a Japanese firm to provide technical information

and training. Our own shipyard would be responsible for the adaptation of

existing equipment and the construction (and purchase) of new equipment needed

for this method. Finally, ABS approval will be needed before this technique is

adopted in actual production. The implementation of line heating will require

approximately one year.

Upon approval of this proposal I will prepare a detailed procedure and cost

estimate for implementation of line heating technology. Final cost estimates can be

made after technical training with the Japanese firm. Qualitative benefits then can

be calculated for selected proposals and contracts, based on the percentage of shell

plates which could be formed in whole or part by line heating.

I have schedule a meeting in the Administrative Conference Room for 0900 16 July1986 to discuss this proposal and implementation plans.

Vertical Spacing andType Size• Do not accept the default (‘auto’) vertical

space settings.

Word spacing, justification mode, and line length:

• Ideally, word spaces should be about the width of the narrowestcharacter of a font, i.e. the width of the lower case ‘i’ in serifsand slightly less in sans serif.

• Software packages tend not to allow much control over the word spacing of justified text. This makes hyphenation necessary.

• Local changes in text spacing can greatly alter the ‘color’ orappearnace of a typeface in text.

Visualism

• Typography is the visual representation of language.Identify and express the correlation between language (the spoken word) and typography (the mass-produced word).

• Make it beautiful!Emphasize the internal correlations: the typographic shapes, proportions and shapes of white spaces, and variations in allthe components.

• Use inflection and emphasis in messages we hear and see.

• Make the message accessible, clear, and interesting.
